aircraft and is valid;
10. the aircraft complies with the latest revision of its type design approved by the CAA;
11. if required, the aircraft holds a noise certificate corresponding to the current
configuration of the aircraft in compliance with Subpart I of Annex I (Part-21) to
Regulation (EU) No 748/2012.
(l) The airworthiness review of the aircraft shall include a physical survey of the aircraft. For
that survey, airworthiness review staff not appropriately qualified in accordance with
Annex III (Part-66) shall be assisted by such qualified staff.
(m) Through the physical survey of the aircraft, the airworthiness review staff shall ensure
that:
1. all required markings and placards are properly installed;
2. the aircraft complies with its approved flight manual;
3. the aircraft configuration complies with the approved documentation;
4. no evident defect can be found that has not been addressed in accordance with
point M.A.403;
5. no inconsistencies can be found between the aircraft and the documented review of
records referred to in point (k).
(n) By derogation from point (a), the airworthiness review may be anticipated by a maximum
period of 90 days without loss of continuity of the airworthiness review pattern, so as to
allow for the physical review to take place during a maintenance check.
(o) The airworthiness review certificate (CAA Form 15b) or the recommendation for the issue
of the airworthiness review certificate (CAA Form 15a) referred to in Appendix III to this
Annex can only be issued:
1. by authorised airworthiness review staff on behalf of the approved organisation;
2. if the airworthiness review has been completely carried out.
(q) Airworthiness review tasks shall not be subcontracted.
(r) Should the outcome of the airworthiness review be inconclusive, the organisation having
carried out the review shall inform the CAA as soon as possible and in any case within 72
hours from the moment the organisation identifies the reason for which the airworthiness
review is inconclusive.
(s) The airworthiness review certificate shall not be issued until all findings have been closed
M.A.901 AMC Aircraft airworthiness review
In order to ensure the validity of the aircraft airworthiness certificate, M.A.901 requires performing
periodically an airworthiness review of the aircraft and its continuing airworthiness records, which
results in the issuance of an airworthiness review certificate valid for one year.
M.A.901 GM Airworthiness review
Responsibilities of airworthiness review staff:
The following is a summary of the requirements contained in M.A.901 as well as the associated AMC
and Appendices, in relation to the responsibilities of the airworthiness review staff:
- Airworthiness review staff are responsible for performing both the documental and the
physical survey. First numbered paragraph. Use ListLevel0 style.
- Procedures must be established by the CAMO or CAO in order to perform the
airworthiness review, including the depth of samplings.
- Procedures must make very clear that the final word about the depth of the inspections
(both documental and physical) belongs to the airworthiness review staff, who can go
beyond the depth established in the CAME or CAE if they find it necessary. At the end, it is
the responsibility of the airworthiness review staff to be satisfied that the aircraft complies
with PartM and is airworthy, and the organisation must ensure that no pressure or
restrictions are imposed on the airworthiness review staff when performing their duty.
- A compliance report must be produced by the airworthiness review staff, detailing all
items checked and the outcome of the review.
- Airworthiness review staff are responsible for the items checked during the airworthiness
review. However, they do not take over the responsibilities of the CAMO, maintenance
organisation, DOA, POA or any other organisations, not being responsible for problems
not detected during the airworthiness review or for the possibility that the approved or
declared maintenance programme may not include certain recommendations from the
design approval holder. Obviously, if the airworthiness review staff are not independent of
the airworthiness management process and were nominated on the basis of the option of
having overall authority on such a process, they will be responsible for the full continuing
airworthiness of such aircraft. Nevertheless, this responsibility will be a consequence of
their position in the organisation and not of their function as airworthiness review staff.
- The issuance of the airworthiness review certificate (ARC) by the airworthiness review
staff only certifies that the aircraft is considered airworthy in relation to the scope of the
airworthiness review performed and the fact that the airworthiness review staff are not
aware of instances of noncompliance which endanger flight safety. Furthermore, it only
certifies that the aircraft is considered airworthy at the time of the review.
It is the responsibility of the owner or contracted CAMO or CAO to ensure that the aircraft is fully
airworthy at any time.
