Aircraft and Ownership

In this item we try to provide useful information, or sources of information, related to the ownership, including purchase and maintenance, of an Aircraft in the UK.

The content is arranged in separate subject areas in the accordion sections below.

If you think we should include additional information or have got something wrong please Contact Us and let us know.

This article is intended to provide basic advice on the purchase of a typical light GA aircraft, either factory built or as a kit build project, including a part built kit.

AOPA members may Ask AOPA for further advice.

On the face of it, purchasing an aircraft should be as straight forward a buying a vehicle or a property.

We suggest this as a basic pre-purchase check list is:

  • Determine what aircraft you want to purchase
  • Decide if you are buying new or used, factory built, kit or part built to complete
  • If you are buying new, contact the manufacturer or their authorised agent/s for your locale
  • If you are buying used, even if potentially buying from someone you know, you are advised to investigate the current market place for other examples
  • If you are taking out finance for the purchase, as a mortgage on the aircraft, get an in principle offer
  • Get quotes for Aircraft Insurance
  • Confirm that you have agreed somewhere to base the aircraft
  • Obtain as much detail about the aircraft as possible, including other pilots of this type of aircraft
  • If the aircraft is already registered:
    • check the relevant National Aircraft Register (do a web search. In the UK it is the GINFO Database)
    • contact the Registered Owner to confirm the aircraft is for sale as advertised
    • check if there is any outstanding Mortgage on the aircraft
    • If it is/was an EASA Aircraft check what Airworhiness Directives apply. EASA have this tool. Use advanced search to select the aircraft make, type and model.
  • Carry out a first Inspection the Aircraft (or part build) and documents
  • Follow up with a detailed inspection, perhaps with an Aircraft Engineer or Surveyor, and test flight.

VAT on Aircraft Purchases

Since leaving the European Union on 31 Deecmber 2020 the UK has become  an independent Customs and Excise territory leaving behind the common EU customs arrangements.

As of the 31st of December 2020, goods in the United Kingdom became known as domestic goods whereas goods that were in the European region where known as EU goods.

Therefore, goods coming into the UK are treated as imports and are subject to, in certain circumstances, tariffs and VAT.

If you decide to purchase an aircraft from an EU member state as a private individual from a private individual when you import that aircraft, it will be subject to VAT even where VAT has been paid in Europe. If the goods had previously been in the United Kingdom and proof of VAT paid is available then paying VAT again may be avoidable but that will be down to individual assessments by HMRC . The only possible VAT recovery route is through a business.

HMRC is unable to say how EU customs agencies will act. This is because they have no working arrangements with officials in Europe. Therefore, you may need to show proof of VAT being paid. We are currently waiting further advice from HMRC in respect of VAT and the Free Circulation status of "G" Registered aircraft in Europe.

There are other issues in respect of importing goods that we hope to be able to update you on in the future but it is safe to say the importing and exporting aircraft  from the EU is now the same as if you were doing it from any other parts of the world.

We are waiting for HMRC to confirm this so more will follow at the right time.

You may be able to reclaim the VAT paid on goods and services purchased for use in your business.  If at any time VAT is reclaimed then subsequent sales may attract VAT again for private purchases or non-VAT registered businesses.

The main options available for financing the purchase of an aircraft are:

  • Cash
  • Bank overdraft
  • Capital loans
  • Export credit loans

Some common structures for financing an aircraft are:

  • Loans secured by a mortgage
  • Finance and operating leasing
  • Pre-delivery payment financing

There are many companies offering finance for the purchase of an aircraft. The majority will require the loan to be secured on the aircraft by a mortgage. The terms vary, subject to your status, so it is a good idea to shop around.

If you are buying your aircraft through a broker they may also offer to arrange finance. If you use such a service, make sure you understand any terms and administration costs they might add or commission they may be receiving. You may get a better deal dealing direct.

Aircraft Mortgages are covered by legislation in the UK: Statutory Instruments 1972 No. 1268 CIVIL AVIATION The Mortgaging of Aircraft Order 1972

All aircraft must be registered. In the UK the legislation is covered in: Statutory Instruments 2016 No. 765 CIVIL AVIATION The Air Navigation Order 2016

There are specific requirements for each of the following kinds of aircraft:

  • New Homebuilt Aircraft
  • New Foreign Manufactured Aircraft
  • Used Foreign Registered Aircraft
  • New UK Manufactured Aircraft
  • Former UK Registered Aircraft never Registered elsewhere
  • Gliders

See the UK CAA website for registering an aircraft in the UK.

You may require a radio licence to be issued for your aircraft. Aeronautical Radio Licences are not transferable, so licences held in the previous owner's name are not valid. See the Ofcom website for more details.

If your aircraft will be, or is, subject to a mortgage you may enter a new aircraft mortgage on to the register. See the UK CAA website for more details.

A pre-purchase inspection of an aircraft that you are seriously considering buying can be a valuable tool in negotiation with the owner. You should approach a suitable Aircraft Engineer to ask if they would carry out an inspection for you and under what terms and cost. You may not find an engineer willing to put anything in writing in case of possible litigation against them on the basis of their inspection. However, you should make sure the engineer has a clear understanding of your expectations and you of his/hers, including any limitations.

There is normally a going rate per hour plus expenses. A licensed engineer is not essential, as many unlicensed engineers employed in a maintenance organisation have a wealth of experience. You might also consider approaching local groups operating an aircraft similar to one you are interested in, as such a group usually has a co-owner who looks after the engineering side, and they are often quite knowledgeable. Different aircraft types suffer from known problems particular to that type. Owner club websites are also a good source of information.

The aircraft and engine logbooks (preferably going back to the date of manufacture) need to be made available to your engineer because he/she will be able to tell you a lot about the aircraft simply from its recorded history. He/she will also examine the logbooks to check that all the correct maintenance has been properly carried out, and that all the ADs and SBs (Airworthiness Directives and Service Bulletins) have been attended to. If the aircraft has flown much less than 100 hours per year for considerable periods in the last few years, then beware of engine corrosion problems. Many owners do not take kindly to their aircraft being dismantled in order for a third party to investigate its airworthiness, and in this case an inspection relies mainly on what can be viewed externally or seen via inspection panels. But, if the underside of the aircraft is dirty or muddy, beware of superficial corrosion of the skins (assuming an aluminium structure) indicated by little bubbles under the paint. Check the state of the interior and the avionics fit, because this has an impact on the value, as does the total hours on the airframe and particularly the engine. Bear in mind that bringing an engine back to zero hours, together with renovating all the ancillaries may set you back £15k plus or minus depending on type. Different engines have differing TBOs, so an aircraft with an engine coming up to the end of its TBO life, or calendar life if that is closer, is worth that much less that one with a brand new engine. A new paint job will set you back £6000 or more.

A typical pre-purchase inspection may cost something of the order of £300 plus expenses, and will vary according to factors such as depth of inspection required, selling price and complexity of the aircraft. Twin–engine aircraft, and aircraft with retractable gear, de-icing, variable pitch propeller etc. will inevitably cost more. You should expect to cover the engineer’s expenses, typically travel and subsistence. Remember the basic price quoted above is roughly equivalent to the labour costs for a 50-hour check inspection - the pre-purchase inspection at this level cannot be expected to uncover problems that may only come to light at an annual check, which is much deeper than a 50-hour. If asked, your engineer may (or may choose not to) offer a valuation – do not expect one in writing, though. He/she may also recommend that you avoid purchasing the aircraft altogether (again, not in writing) and in this case you would be wise to heed his/her advice, even though that advice has cost you money.

There are three basic routes from which to choose if you wish to build your own aircraft, including Helicopter and Microlight:

  • Design and build your own aircraft from scratch
  • Construct an aircraft from plans designed by someone else
  • Assemble a kit

CAP 659: Guide to Approval, Construction and Operation of Amateur Built Aircraft is a comprehensive guide to the rules around amateur built aircraft, providing an acceptable means of compliance. It is relevant to anyone who:

  • seeks a Permit to Fly for an amateur built aircraft.
  • is restoring an aircraft (which is not eligible for a Certificate of Airworthiness) and seeks a Permit to Fly for it, be it an existing amateur constructed aircraft, or an historic aircraft whether factory built or otherwise and irrespective of whether it was originally built in the UK or has been imported.

The CAA approves all amateur built aircraft. The route to achieving approval is either by the CAA conducting a direct investigation of the aircraft or, for certain simpler types of aircraft, via the BMAA or LAA conducting the investigation on their behalf. At the end of the BMAA or LAA investigation the CAA issue the approval on the basis of their recommendation.

CAP 659 applies to anyone who seeks a Permit to Fly for an amateur built aircraft, but it only describes the processes that should be followed where the CAA is directly involved in the investigation and approval of the aircraft. Cross-reference may be made to BMAA and LAA processes, but no attempt is made to define them. Amateur builders who wish to know what those processes involve are advised to contact the BMAA or LAA direct.

Under Part 4 Airworthiness of Aircraft Chapter 3 of the Air Navigation Order 2016 , no aircraft may fly in the UK unless, subject to certain exceptions, it has a valid Certificate of Airworthiness (C of A) or a valid Permit to Fly.

An amateur built aircraft cannot qualify for the issue of a Certificate of Airworthiness because it would not in its entirety have been designed and constructed by an appropriately qualified organisation as required by:

  • ICAO Annex 8; and
  • British Civil Airworthiness Requirements; and
  • EU Regulations Nos. 1592/2002 (establishing EASA) and 1702/2003 (the EASA Implementation Regulations); and
  • EASA Certification Specifications (CSs).

The level of airworthiness achieved by both the design and during the building process is variable and because of this the CAA do not consider it appropriate to issue a C of A to such an aircraft. The CAA will, however, consider as an alternative the issue of a Permit to Fly under the requirements of BCAR Chapters A3-7 or B3-7, when we are satisfied that the criteria of BCAR Chapters A3-7 or B3-7 have been met.

Before you can fly an aircraft it is required by law to have minimum levels of insurance. The  level of insurance cover  depends on the Maximum Take-Off Mass (MTOM) of the aircraft and on the number of passengers carried.

On 30 April 2005, EC Regulation EC 785/2004 on insurance requirements for air carriers and aircraft operators came into force. The Regulation was subsequently amended on 6th April 2010. The Regulation, as amended, specifies the minimum levels of insurance required by aircraft operators and air carriers in respect of third party cover, passenger cover and cover for risks of war and terrorism.

In the United Kingdom the Civil Aviation Authority (CAA) is the designated authority for monitoring compliance with the regulation on behalf of the Department for Transport (DfT).

The relevant regulation:

Aircraft insurance must cover:

  • passengers
  • baggage
  • third party cover
  • cargo (if relevant)
  • risks of war and terrorism (‘war risk’) - unless exempted

The minimum level of insurance cover is based on an International Monetary Fund "Special Drawing Right"  (SDR) international currency unit. To convert to GBP, You can find the current exchange rate here

The minimum value of insurance can then be calculated:

MTOM    (kg)          Minimum Insurance (Million SDRs)

*Up to 499                                    0.75
500 -999                                       1.5
1,000 - 2,699                                 3
2,700 - 5,999                                 7

* Aircraft and micro-lights with a MTOM of less than 500 kg used for non-commercial purposes or used for local flight instruction which does not involve crossing international borders are not required to insure against war and terrorism (war risk). Check Regulation (EC) No 785/2004 for more detail.

For non-commercial operations with aircraft having a MTOM of 2,700 kg or less, the minimum level of passenger insurance shall not be less than 100,000 SDRs per passenger. In all other cases the minimum level of passenger insurance shall not be less than 250,000 SDRs per passenger.

Baggage shall be insured for not less than 1,000 SDRs per passenger.

Cargo shall be insured for not less than 17 SDRs per kg of cargo carried, if relevant.

For a typical 4 seat aircraft, single pilot and 3 passengers, with a MTOM between 1,000 and 2,699 the minimum insurance level would be:

3rd Party Insurance 3,000,000 SDRs
3 Passengers at 250,000 SDRs = 750,000 SDRs
3 Baggage at 1,000 SDRs = 3,000 SDRs
Total = 3,753,000 SDRs. This is approximately £3.44 Million.

However, you may find that there is a much higher minimum insurance requirement at some Airports or Airfields, especially Ministry of Defence properties.

You may also get an estimate of the minimum level of insurance required for a particular aircraft type from the G-INFO database.

Enter the Aircraft type you are interested in and then Search. Select one of the aircraft in list, if there are any listed, and then click Minimum Insurance Requirements for an estimate.

From the CAA website (

"The CAA will normally consider evidence of insurance, and therefore compliance with the Regulation, on the basis of the exchange rate between Sterling and the SDR in place at the inception of the policy. However, owners and operators need to be aware that it is their responsibility to ensure that adequate cover exists for each and every flight. If owners or operators have concerns over their level of cover they should contact their broker for advice."

Obtaining Insurance Quotes:

The Aircraft Insurance market has expanded in recent years and there is now much wider choice for obtaining quotes, which has subsequently seen premiums at least remain stable and possibly reduced.

As with other insurances, you can affect the cost of your insurance by reducing risk. One way is to restrict cover to named pilots only with minimum levels of PIC hours, in particular hours on type.
On renewal, shop around for comparable levels of cover to check that you are still getting a good deal from your Broker.

There may be other ways to keep your premiums down. Speak to your Broker for advice.

Within the UK, other than those aircraft deemed to be deregulated, require a Certificate of Airworthiness (CoA) or Permit to Fly based upon the correct maintenance being undertaken.

GA Aircraft requiring a CoA/Permit to Fly will fall into these categories:

  • Part-21 Aircraft
  • Non Part-21 Aircraft (Operating on a Permit to Fly)

An ELA1 Aircraft is:

  • an aeroplane with a MTOM of 1,200 kg or less and is not a complex motor-powered aircraft
  • a sailplane or powered sailplane of 1,200 kg MTOM or less
  • a balloon with a maximum design lifting gas or hot air volume of not more than 3,400 cu.m for hot air balloons, 1,050 cu.m for gas balloons, 300 cu.m for tethered gas balloons
  • an airship designed for not more than 4 occupants and a maximum design lifting gas or hot air volume of not more than 3,400 cu.m for hot air airships and 1,000 cu.m for gas airships

Developed with input from the AOPA Maintenance Working Group, The Airworthiness Code; A maintenance guide for light aircraft is a guidance document designed to support owners and operators of general aviation (GA) aircraft.

The document primarily addresses Part 21 aeroplanes and rotorcraft subject to the Part-M regulation; and Part 21 aircraft operating on an enduring permit to fly.

Aircraft Maintenance Part-M and Part-ML.

On 24 March 2020 Consolidated Regulation (EU) No1321/2014 on Continuing Airworthiness came into effect for EASA Aircraft. The regulation separates the existing continuing airworthiness requirements for 'Light Aircraft' from the requirements applicable for licensed air carriers and other complex motor-powered aircraft. See also EASA Easy Access Rules for Continuing Airworthiness.

Annex Vb (Part-ML) of the regulation applies to the following other than complex motor-powered aircraft not listed in the air operator certificate of an air carrier licensed in accordance with Regulation (EC) No 1008/2008, i.e. in effect an airline:

(1) aeroplanes of 2730kg maximum take-off mass (MTOM) or less;
(2) rotorcraft of 1200kg MTOM or less, certified for a maximum of up to 4 occupants;
(3) other ELA2 aircraft.

The owner of the aircraft is responsible for the continuing airworthiness of the aircraft and shall ensure that no flight takes place unless all of the following requirements are met:

(1) the aircraft is maintained in an airworthy condition;
(2) any operational and emergency equipment fitted is correctly installed and serviceable or clearly identified as unserviceable;
(3) the airworthiness certificate is valid;
(4) the maintenance of the aircraft is performed in accordance with the Aircraft Maintenance Program (‘AMP’) specified in ML.A.302.

The owner of the aircraft may contract the tasks above to an organisation approved as a Continuing Airworthiness Management Organisation (CAMO) or Combined Airworthiness Organisation (CAO).

For aircraft operated by commercial Approved Training Organisations (ATO) or a commercial Declared Training Organisations (DTO) or not operated in accordance with AnnexVII to Regulation (EU) No 965/2012 (Part-NCO) or operated in accordance with Subpart-ADD of Annex II (Part-BOP) to Regulation (EU) 2018/395 or Subpart-DEC of AnnexII (Part-SAO) to Regulation (EU) 2018/19761, the operator shall:

(1) be approved as a CAMO or as a CAO for the management of the continuing airworthiness of its aircraft in accordance with Annex Vc (Part-CAMO), Subpart G of AnnexI (Part-M) or Annex Vd (Part-CAO), or contract such an organisation using the contract set out in Appendix I to this Annex;

(2) ensure that all maintenance is performed by maintenance organisations approved in accordance with point (c)(2) of point ML.1.;

(3) ensure that the requirements of point (a) are satisfied.

For most aircraft owners, the continuing airworthiness responsibilities will probably be contracted to a CAMO or CAO and the maintenance is performed by a maintenance organisation. All owners interested in their aircraft maintenance as well as owners who manage their own continuing airworthiness should read Annex Vb (Part ML) and the associated AMC and GM Owners who want to change the maintenance tasks being performed on their aircraft or the frequency of that maintenance should contact their CAMO/CAO to see if Part-ML allows them to revise the Aircraft Maintenance Programme (AMP). Additionally, if you want to be included in the AMP to perform pilot-owner maintenance, you should contact your CAMO/CAO.

Under Part-ML, if your agreed AMP uses a risk based approach to maintenance (obviating the requirements of CAP 747), then an engine on an aircraft used for flight training can continue to be operated on condition if the AMP includes a series of sensible checks. For example, these can include cylinder compression measurements, monitoring oil consumption and an oil analysis at each check. It also means that the engine could be more than 12 years old.

See also the CAA Part-ML webpage.
If the AMP has been agreed with a maintenance organisation and the owner has been charged for the time by the maintenance organisation then the AMP belongs to the owner, and can be used as the basis of the agreed  AMP with a new maintainer. Otherwise, the AMP belongs to the maintenance organisation. 

Non Part-21 Aircraft: UK Permit to Fly issued by the LAA or BMAA

Permit to Fly Aircraft (LAA Permit)

LAA Permit Aircraft are issued with a Permit to Fly by the CAA based on LAA Recommendations.

The Permit to Fly is non-expiring but has a certificate of Validity which is reviewed annually.

The owner must ensure that the aircraft is maintained to a schedule, or programme, agreed with the LAA.

Maintenance must be signed off by an LAA Inspector approved for the aircraft type.

Permit to Fly Aircraft (BMAA Permit)

BMAA Permit Aircraft are issued with a Permit to Fly by the CAA based on BMAA Recommendations.

The Permit to Fly is non-expiring but has a certificate of Validity which is reviewed annually.

The owner must ensure that the aircraft is maintained to a schedule, or programme, agreed with the BMAA.

Maintenance must be signed off by a BMAA Inspector approved for the aircraft type.

Ex-Military Aircraft

The CAA issues the Permit to Fly, see CAP 1640.

A Certificate of Validity will normally be issued by the CAA on recommendation.

Correct as at 9 March 2023

If an STC was approved by EASA prior to 31 December 2020 it is considered approved by the CAA and has not been published on the CAA website.

If an STC has been issued post this date it needs to be approved, validated or accepted or in accordance with the FAA/CAA IPA here:  

The STC holder needs to apply using this form:  

In all cases, the STC holder has to apply for validation in the UK

If the STC holder does not wish to apply for a validation, an owner can apply for a minor change to approve the STC for a single serial number (depending on the complexity of the STC) using the form above.

The UK CAA advised that after the UK left EASA the following would apply:

"The text of the regulation allows, in unforeseen circumstances, the owner to authorise a person with proper qualifications and experience to maintain and release the aircraft. The owner is responsible for getting the maintenance rechecked within seven days and keeping all the records of the maintenance and the qualifications of the person who did the maintenance. If a continuing airworthiness management organisation is involved, the owner must inform them within seven days (or 30-Days in certain circumstances). The full regulation is in Part-145.A.50 (f), M.A.801 (c) or ML.A.801 (c)"

EASA Easy Access Rules for Part-145.A.50 (f), M.A.801 (c) or ML.A.801 (c).

One of the most regular requests AOPA UK gets from members is to resolve disputes between aircraft owners and maintainers. The AOPA Maintainers Working Group have produced a Code of Practice for Maintenance and Repair that they themselves will follow, and which can be signed up to by light aircraft maintainers.

Many disputes arise from unrealistic expectations on the part of owners. A common understanding prior to the commencement of work is desirable.

If an aircraft maintainer is not signed up to the AOPA Code of Practice ask why not! Be wary of any organisation that refuses to give any such, or similar, commitment to you as a Customer.

An aircraft owner who is a customer of a light aircraft maintenance organisation that subscribes to the AOPA Code of Practice for Maintenance and Repair is provided the following commitment:

AOPA Code of Practice for Maintenance and Repair

  • We will endeavour to contact you at least two weeks in advance of any scheduled maintenance due to fix a mutually acceptable time and date to receive your aircraft at our facility.
  • A full explanation of any mandatory requirements ADs, SBs, etc. that you need to have carried out when your aircraft is with us, in addition to the routine scheduled work, will be given in detail.
  • Any additional work requested by you will be agreed at the time of booking.
  • Estimates and quotations can be provided upon request and before any work is carried out if required.
  • Accepted methods of payment will be confirmed prior to any work commencing. (For lengthy or expensive projects stage payments may be agreed)
  • We will agree with you the parts to be used. Should you wish to source and pay for parts directly this can be discussed and we may be able to agree, subject to the inclusion of a suitable administration fee to cover the approval of any necessary paperwork that you need to provide.
  • All parts supplied by us remain our property until we are in receipt of cleared funds.
  • Replaced parts will be made available to you for examination upon request. (Unless required for part exchange by our supplier.)

The Maintenance Organisations below have signed up to the AOPA Maintenance Code of Practice.

The December 2016 issue of the AOPA Magazine included an introductory article on the Self-Declared Maintenance Programme (SDMP) for EASA aircraft of MTOM 1200kg (ELA1) used for private flying.

The next time your aircraft goes in for its annual service, your maintainer should seek your views on the Maintenance Programme (MP) to be adopted. Since October last year, it has been an EASA requirement that each aircraft has a specific MP that is declared by the owner to be appropriate, the SDMP.

It is to your advantage to take the time to work through this with your maintenance organisation. Of course, you can simply ask your maintenance organisation to sort it out without your guidance or involvement, but the MP may end up being more comprehensive than is practically necessary.

You are likely to be charged for the time to complete the forms to set up your aircraft-specific MP, so why not take the opportunity to learn more?

To make a self-declaration,it is useful to complete the EDD 2015/024/R form from the CAA website, which explains the basis of any MP in a standard format.

The CAA do not review or approve any maintenance programme; this is now the responsibility of the owner. Note also that any annual service has to be signed off by a licensed engineer, so your MP will need to be agreed with them.

The CAA simply file the declaration away in case it needs to be looked at in the future. If your aircraft has a maintenance schedule provided by the manufacturer, you, or your maintainer, can use this as a basis on which to start formulating your aircraft’s MP. Note that the manufacturer’s maintenance schedule might not be available directly to the private owner as many manufacturers provide the appropriate technical publication only through a specialised US provider, APT (Aircraft Technical Publications), which your maintainer hopefully subscribes to.

EASA have defined a Minimum Inspection Programme (MIP) that any MP must satisfy, so yours will lie in between.

A manufacturer has to assume that an aircraft can be used in a range of environments and operating conditions, perhaps being stored outside, maybe in arctic, coastal or desert conditions, with some pattern of assumed usage. But your aircraft may be stored in a warm hangar and flown just 50 hours a year, so the maintenance requirements might not need to be so demanding.

So the opportunity now exists to have a slimmed down MP that is fit and suitable for your aircraft, with unnecessary aspects removed and others reduced in scope or frequency to meet your situation.

You may, however, wish add in some checks and procedures to cover particular operational aspects, e.g. more frequent landing gear checks when operating out of a very bumpy airfield.

So dig out the CAA form; immediately you can draw a line through many of the boxes as you are not a balloon and only have an ELA1 etc. Then take a careful look at the manufacturer's or current maintenance schedule and question each part. This is where you need to get together with your maintainer, removing all that does not apply. Time spent establishing the most appropriate MP will save you money in future years.

No doubt there will be some one-off costs involved in setting up your SDMP but the overall aim is to allow more relevant MPs to exist for each aircraft. So create the MP that works well for you and your aircraft.

This article is written for non-commercial operations and non-complex aircraft. The parts pertaining to changes made in the Air Navigation Order 2016 have been written with advice from and review by the CAA.

If you are a commercial operator and a member of AOPA UK you should contact us if you have a specific enquiry.

Prior to the Air Navigation Order 2016, for any Aircraft that was not subject to a Certificate of Airworthiness there was a minimum shareholding of 5% if the owners wanted to take advantage of the exception  in Article 269. For Aircraft with a Certificate of Airworthiness this limit did not apply so long as the aircraft was maintained to Public Transport standards.

The Air Navigation Order 2016 no longer stipulates any minimum share value.

It is a requirement for a group that all owners of an aircraft are notified to the CAA using the appropriate form. Not all shareholders in an aircraft appear on the UK Register.

Aircraft can be registered in the names of multiple owners without it being registered as a Group. However, if there are more than three joint owners it is probably best that the aircraft is registered to the trustee of the assets of the group. The trustee must have a share in the aircraft and that person is deemed to be the legal owner of the aircraft. The other shareholders are beneficial owners and, as such, do not have to appear on the Register itself. However, the CAA must be informed of all shareholders and changes that may subsequently occur.

To be registered as a Group, one of the owners must be nominated as a trustee of the Group and then you can add or remove group members without having to re-register the aircraft. If the trustee leaves the group then the aircraft does have to be re-registered.

Group ownership allows the aircraft to be better utilised, reducing the overall hourly cost of flying when both direct and annual costs are considered. However, unless the group members are carefully chosen it can be a bad option.

For national permit to fly aircraft, there must be a permission (general or individual) from the CAA in order to be hired out to another pilot. If the pilot flying the aircraft is a joint-owner, then no such requirement applies. In order to be considered to be a joint owner they must:

  • Own equity in the aircraft; and
  • Either be a registered owner or in the case of an aircraft registered to a trustee, the trustee must have notified the CAA of the owner joining or leaving of the group.

Under the ANO 2016, there is no longer a direct limit of 20 owners before a group would be considered a self-fly hire arrangement. Whilst it may appear that you can set up a group with unlimited numbers with registered owners having a very notional financial interest in the aircraft, a sensible approach should be adopted such that a group arrangement between joint owners remains as such, and does not appear to be effectively self-fly hire concealed through notional amounts of equity that might change hands on a short term basis. Arrangements that have a very high number of owners and/or frequent changes of group members might arise suspicion and should be avoided.

The CAA has a page about Group Ownership with appropriate links here.

Any owner or beneficial owner of the aircraft can then:

1. Self-Fly the Aircraft (subject to ratings and differences training if required)

2. Pay the *Direct Costs for the flight on an hourly basis.

3. Pay a proportion of the Annual Costs. To be seen to be proportional this should be an hourly sum calculated as an hourly cost by dividing the annual costs by the estimated number of annual flying hours.

*Direct Cost

The cost directly incurred in relation to a flight, e.g. fuel, airfield charges, rental fee for an aircraft. There is no element of profit.

*Annual Costs

Annual cost means the cost of keeping, maintaining and operating the aircraft over a period of one calendar year. There is no element of profit.

Group Arrangements

Effectively, there are two ways of managing group ownership of an aircraft.  The first of these is a joint, or co-ownership, arrangement and the second is by means of a limited liability company.

There are usually three concerns to be addressed by private owners when deciding how to structure their group.  These are cost, ease of administration and the important issue of liability to third parties.

As far as costs are concerned, it is fair to say that the co-ownership arrangements should be cheaper than the costs of incorporating a company and the need for various filings to be made at Companies House.  However, whether a co-ownership group or a company, it is vital that the members agree a formal and properly drafted agreement between them, which should deal with a number of important questions.  A properly drafted members', or if appropriate shareholders’ agreement should deal with:

  • membership entitlement
  • for joint owners with a financial share, the sale of either shares in the aircraft or, if a company, shares in the company
  • treatment of equity members versus non-equity members
  • retirement from membership
  • the provision of audited accounts
  • the frequency of meetings and the ability of a number of members to call meetings
  • the management of the group, with clear administrative responsibilities
  • insurance and indemnity arrangements
  • expulsion from the group

When setting up the agreement careful consideration must be given to the question of borrowing.

Borrowing by the group or the company should normally be by unanimous consent of the group members or shareholders only.

Insofar as administration is concerned much, of course, depends on the goodwill of persons involved to ensure the group is run smoothly. To avoid future difficulties adequate provision should always be made for each and every member to be kept fully informed and, most importantly, to be sent a copy of the insurance policy each and every year as it is renewed and to be made fully aware of its terms, conditions and exclusions.

The corporate structure involves more administration in that there are regular filings, which need to be made at Companies House, and annual accounts must be prepared and submitted along with an annual return.  However, recent amendments to the companies legislation has made provision for a much simplified form of company accounts to be prepared.

There is also the question of transfer of interests.  If a company has its liability limited by shares, then a formal transfer of the shares must be made with appropriate entries in the company's books.  Should the co-ownership agreement be adopted then some of these formalities are unnecessary, but it should be remembered that the CAA must be informed of every change to the co-owners who is also a trustee, then an appropriate amendments needs to be made on the aircraft register.

In any event, whether a co-ownership or corporate structure is adopted, full and up-to-date financial data should be readily available to its members at all times.

The next issue is the tricky one of the potential liability of the aircraft owners to any third party who is injured or killed or whose property is damaged as a result of an accident involving the aircraft.

It is in this particular area that, in an attempt to reduce insurance cost and potential liability, many individuals favour the corporate structure rather than co-ownership.  It has been clearly established for nearly a century that a company is treated in the eyes of the law as an entity wholly distinct from the persons who are its members.  Because a company is treated as a distinct entity, one of the principal advantages of trading through this medium has always been that the members of the company are only liable to contribute towards the payments of its debts to a limited extent.  It therefore follows that if a company is unable to pay its debts, because for example, its insurance cover is inadequate, an unpaid creditor may petition the court to wind it up.

If an order is made, a liquidator will be appointed to realise the company's assets (in the present case, usually only the aircraft) and if he realises insufficient to pay its debts he will call upon its shareholders to make good any deficiency; their liability is limited to the balance of capital unpaid on the shares (if any) plus any unpaid premiums.  This will usually be little or nothing.

However there is a certain limitation to the protection that can be derived from the company structure.  Take the following example:

There is an accident involving, an aircraft which is jointly owned.  The accident was caused by a mechanical defect in the aircraft which was known by one of the members, who was charged with having the defect rectified but who did nothing about it.  It is likely that, in such a circumstance, not only would the company be sued but also the person who was negligent in failing to rectify the defect and also, possibly, the pilot in that he should have made appropriate checks to ensure that the aircraft was airworthy.

Where does this leave the other innocent members if the company is sued?

While there might be some liability upon the company as owner of the aircraft, a properly drafted agreement would provide for a right for the company to seek redress or indemnity from the guilty parties.  It is possible that those guilty individuals would be sued by the parties and may be made bankrupt.  In these circumstances the indemnity would be worthless.  The litigant might then look to the company for payment of all damages and, if necessary, petition for the winding up of the company and sale of its only asset i.e. the aircraft.  However, the members would be able to limit their individual liability as before.  This is slightly different from the position with co-owners who risk not only losing the aircraft but would also be personally liable, their only rights being by way of contribution from the other members.

The corporate structure, therefore, will not absolve the individual from liability for his own culpable negligence but may protect the other innocent shareholders.  However, there is no substitute for procuring full third party legal liability insurance and ensuring that each member who operates the aircraft adheres fully to the terms and conditions of the policy: underinsurance can have disastrous consequences, as can breach of policy terms.

It is always important to ensure that the company trades only when solvent and is able to pay its debts as they fall due, thereby avoiding some of the pitfalls which directors of companies find themselves in under the draconian provisions of the new insolvency legislation.

As you will see there are many factors to be considered when finalising a joint ownership structure.  One vital factor is the likely number of participants.  Two individuals, who know and trust each other, may prefer the looser arrangement which co-ownership offers.  However, on balance, I would always recommend the use of a company, especially if there are a large number of participants.  The most important lesson for any party considering a joint ownership is that the arrangements are given careful and proper thought.  Lawful operation and full insurance must always be paramount aims.

Group Arrangements by ROBERT RICKETTS, a Partner and Solicitor in the aviation law firm of Clark Ricketts, London (September 1996)

Updated reference to ANO 2016  by M Elborn, AOPA UK (September 2016), with advice from and review by the CAA.

Aviation Law is contantly changing and you should verify that any information given below is still valid. Fortunately the underlying principles tend to remain constant even if the paragraph and section numbering changes.

Can I rent out my aircraft?

UK National Permit to Fly General Aviation (GA) aircraft can now be used in certain circumstances for remunerated commercial training and self-fly hire. See ORS4 1510 for full details

Type Approved Microlights and Gyroplanes may also be used for Flight Training or Self-Fly Hire. See ORS4 1508 for full details.

UK Registered Part-21 Aircraft  must have either a Certificate of Airworthiness or be a type approved permit to fly aircraft which is already permitted to be used for self fly hire within the terms of the relevant exemptions. UK Regulation applies.

Self-fly hire of a UK Registered Part-21 aircraft is deemed to be a commercial operation if the following applies:
Reference: Regulation (EC) No 216/2008 ('the Basic Regulation'), Regulation (EU) No 965/2012 on Air Operations

The term 'commercial operation' is defined in Article 3 of the Basic Regulation as follows:
 'Commercial operation' shall mean any operation of an aircraft, in return for remuneration or other valuable consideration, which is available to the public or, when not made available to the public, which is performed under a contract between an operator and a customer, where the latter has no control over the operator.

If your UK Registered Part-21 aircraft is operating with an engine beyond TBO, or is older than permitted years, you may be restricted to private use only. For information about operating an aircraft "on condition" see CAP 747. In particular, see Section 3.1. Note that Issue 3 2017/01 still refers to ANO 2009 and the term  "Aerial Work". In response to a specific enquiry from AOPA,  Neil Peacock, Principal Airworthiness Surveyor at the CAA has responded;  "My understanding is that 'Aerial Work' is now read as 'Commercial Operations', the intent of GR 24 still applies."

If you are unable to operate your aircraft "on condition" for "Commercial Operations", an alternative would be for the hirer to have some level of share in the aircraft and operate it as a private group. Your maintenance organisation should be able to advise you.

Jointly owned aircraft can be registered in the name of each individual owner, but in cases where there are three or more individual owners of an aircraft it is recommended that you form a group of co-ownership syndicate for the purposes of registration. In this way, any member may leave or join the group without the need to re-register the aircraft every time (which would incur a fee).

One or two of the owners must be nominated as trustee(s) of the group. If a trustee leaves the group or ceases to act as trustee, the aircraft must be re-registered.

Note that 'non-equity' groups cannot be registered in this way as the group members do not hold any ownership of the aircraft itself. In this case, the aircraft should be registered to the owner.

From the CAA website:

"Please note that 'non-equity' groups cannot be registered in this way as the group members do not hold any ownership of the aircraft itself. In this case, the aircraft should be registered to the owner.

The trustee of a group must supply a fill list of names, addresses, nationalities and percentage shareholdings of the group members using a Trustee Grid form.  This must be submitted along with the registration application.

The CAA must be advised by the trustee as soon as any members leave or join the group, which can done by submitting an updated Trustee Grid form by post or email."

If you are an AOPA UK member and need advice on forming a group on your aircraft or self-fly hire of your aircraft please Ask AOPA.

To avoid possible tax benefit in kind implications, assuming that you use the aircraft yourself, if your aircraft is owned and operated as a limited company or trust you should only charge it out at the hourly rate that you pay yourself.

You need to make sure that any other pilot using the aircraft is covered by the aircraft insurance and can legally fly it.

Guidance for private pilots offering charity flights

More UK private pilots will be able to offer flights for charity following a simplification of the Civil Aviation Authority's (CAA) requirements. The Air Navigation Oder (ANO) 2016 and the CAA have issued guidance in CAP 1330.

A blanket permission will now be available for pilots if they meet certain basic requirements. This removes any need for pilots to have to apply to the CAA to carry out individual flights. The changes place more emphasis on pilots providing a thorough explanation to passengers of the level of safety and risks prior to the flight taking place.

As well as simplifying the requirements, other changes include:

  • Extending the types of aircraft that can be used to include permit aircraft such as hang gliders, paragliders, microlights, gyroplanes and powered parachutes, and
  • Allowing flights to take place from unlicensed airfields.

To use the permission, pilots must ensure that they receive no payment for the flight. All money must be paid by the passenger directly to the registered charity and the charity cannot be the operator of the aircraft.

Pilots should also check that their insurance cover is adequate and ask the passenger to check that their own life and any private health insurance covers the intended flight.

Flying Displays

CAP1047 Civil Air Displays - A Guide for Pilots

Before you can perform at an approved flying display you will need a display authorisation. This requires you to undertake an approval flight for a display evaluator.

You now need a behavioural and attitudinal fitness assessment.

CAP 403 has guidance for the organisers of these events and others that do not require CAA permission.

Parachute Dropping

All parachute dropping from civil registered aircraft over the UK is regulated by the CAA and must be conducted in accordance with the requirements set in the Air Navigation Order (ANO) 2016.

CAP 660 : Parachuting is a comprehensive source of information. It collates the rules and regulations and provides guidance on the following topics:

  • Legal requirements
  • Parachuting operations
  • Parachuting displays
  • Monitoring and audit
  • Safety management systems and risk assessment
  • Relevant legislation

CAP 403 "Flying Displays and Special Events" includes further information in relation to parachuting as part of a flying display.

The BPA (British Parachute Association) has compiled an Operations Manual, adherence to which will ensure an acceptable operating standard.
