BMAA Response to CAP553

The BMAA has today responded to the CAA's CAP553 consultation which offers an opportunity to comment on proposed changes to two chapters of the British Civil Airworthiness Requirements (BCAR) which determine the operating parameters within which the BMAA and LAA work. The two chapters are A8-26, which is our Sporting Organisation airworthiness operating approval, and A3-7 Permit to Fly Aircraft – Initial and Continuing Airworthiness.

The consultation document can be read at this link. As you will see it is quite lengthy and complex. We here at the BMAA office have been through it in fine detail and commented on all sections that we feel need clarification or that we disagree with. You can read our response at this link.

We have two significant concerns which we are raising here and asking you to support our response with a personal response from BMAA members.

Appointment and continued authorisation of airworthiness review staff (BMAA Inspectors)

The text below (CAP553 text) which is essentially mirrored in five sections requires a significant change in appointment and validation of BMAA Inspectors and has taken no account of the successful system currently in place. It is difficult for us to see how our current system of largely volunteer inspectors could continue if these requirements are enforced. If this is to be imposed upon the BMAA many of our inspectors would not qualify for appointment and such a loss would be devastating for our membership. We should make it clear here that there has been no pre-consultation discussion between us and the CAA on this matter and no safety case has been made for such a change. If you feel as we do that the requirements as written are disproportionate and unworkable please respond to this consultation and say so.

CAP553 text

A3-7 Para 11.5, A8-26 Paras 2.2.6, 10.2.6, Appendix 2: Experience, Appendix 2: Continued Validity

To be approved to carry out airworthiness reviews, an approved organisation shall have appropriate airworthiness review staff to issue Certificates of Validity, or to make recommendations.

a) The staff shall have acquired:

i) four years of relevant maintenance/continuing airworthiness experience; or

ii) two years if the applicant has satisfactorily completed an appropriate aeronautical maintenance training course.

b) For the issue of a restricted Authorisation, a period of time agreed by the CAA or a person approved by the CAA that will enable a level of competency equivalent to that required by a) to be obtained, provided that this is not less than two years.


Permit Maintenance Release (PMR)

Although not consulted upon directly Chapter A3-7 contains a requirement for certain maintenance carried out by an owner or their agent to be countersigned by an authorised member of airworthiness review staff. The signature is made on a document called a Permit Maintenance Release form. Only a qualified member of the airworthiness review staff, an inspector, can sign the PMR which allows the aircraft to return to service.

Although the PMR system is applied to the LAA fleet it has not up to now been to the BMAA fleet. We believe that the BMAA system that allows owners to nominate individuals whom they believe are considered competent to provide a second signature when required, and not always an inspector, is a safe, pragmatic and more workable way to ensure that aircraft are maintained in a safe condition. We are aware that a system which allows only an authorised member of airworthiness review staff to make such a countersignature is often extremely inconvenient and as such we know that it has been ignored by some owners; this results in the safety net of a second signature being side stepped and so potentially unsafe aircraft to return to service.

We strongly believe that the current system that the BMAA has in place is significantly more workable than the PMR and we ask that if you agree you clearly make the point in your response that there is no evidence put forward as part of the consultation which supports a need for BMAA aircraft to be subject to the PMR requirements. You can read about our tried and tested system in our document Til044. Specifically page 4-15 to 4-24.


Because the CAA have chosen not to consult on the entire chapter A3-7, and because of what we consider an unworkable requirement for the appointment and validation of inspectors we believe that the consultation should stop at this point and that there should be proper engagement with industry representatives to revise both chapters in cooperation with those who are subject to its requirements. If you agree with us please make it part of your response.


In advance, thank you for your support. Every response counts. Responses should be sent to no later than 27 May 2021
