ANNEX I - Continuing Airworthiness Requirements

The above items should clearly state the exact reference of the data used in establishing
compliance; for instance the number and issue of the type certificate data sheet used
should be stated.
The statement should also confirm that all of the above is properly entered and certified in
the aircraft continuing airworthiness record system and/or in the operator’s technical log.
M.A.901(i) AMC Aircraft airworthiness review
Suitable accommodation should include:
(a) an office with normal office equipment such as desks, telephones, photocopying
machines etc. whereby the continuing airworthiness records can be reviewed.
(b) a hangar when needed for the physical survey.
The support of personnel appropriately qualified in accordance with Part-66 is necessary when the
CAA’s airworthiness review staff is not appropriately qualified.

FULL DOCUMENTED REVIEW
1. A full documented review is a check of at least the following categories of documents:
- registration papers;
- M.A.305 aircraft continuing airworthiness record system;
- M.A.306 aircraft technical log system;
- list of deferred defects, minimum equipment list and configuration deviation, list if
applicable;
- aircraft flight manual including aircraft configuration;
- aircraft maintenance programme;
- maintenance data;
- relevant work packages;
- AD status;
- modification and SB status;
- modification and repair approval sheets;
- status of lifelimited parts and timecontrolled components;
- relevant CAA Form 1 or equivalent;
- mass and balance report and equipment list;
- aircraft, engine and propeller TC data sheets.
As a minimum, sample checks within each document category should be carried out.
2. The CAMO or CAO should develop procedures for the airworthiness review staff to
produce a compliance report that confirms the above have been reviewed and found in
compliance with Part-M.
M.A.901(l) and (m) AMC Aircraft airworthiness review
PHYSICAL SURVEY
1. The physical survey could require actions categorised as maintenance (e.g. operational
tests, tests of emergency equipment, visual inspections requiring panel opening, etc.). In
this case, after the airworthiness review, a release to service should be issued.
2. When the airworthiness review staff are not appropriately qualified as per Part-66 in order
to release such maintenance, M.A.901(l) requires them to be assisted by such qualified
personnel. However, the function of such Part-66 personnel is limited to performing and
releasing the maintenance actions requested by the airworthiness review staff, it not
being their function to perform the physical survey of the aircraft.
3. This means that the airworthiness review staff who is going to sign the airworthiness
review certificate or the recommendation should be the one performing both the
documented review and the physical survey of the aircraft. It is not the intent of the rule to
delegate the survey to Part-66 personnel who are not airworthiness review staff.
Furthermore, the provision of M.A.901(n) that allows a 90-day anticipation for the physical
survey provides enough flexibility to ensure that the airworthiness review staff (ARS) are
present.
4. The physical survey may include verifications to be carried out during flight.
5. The CAMO or CAO should develop procedures for the ARS to produce a compliance
report that confirms that the physical survey has been carried out and found satisfactory.
6. To ensure compliance, the physical survey may include relevant sample checks of items.
M.A.901(n) AMC Aircraft airworthiness review
‘Without loss of continuity of the airworthiness review pattern’ means that the new expiration date is
set up 1 year after the previous expiration date. As a consequence, when the airworthiness review is
anticipated, the validity or the airworthiness review certificate is longer than 1 year (up to 90 days
longer).
This anticipation of up to 90 days also applies to the 12-month requirements shown in M.A.901(b),
which means that the aircraft is still considered as being in a controlled environment if it has been
continuously managed by a single organisation and maintained by appropriately approved
organisations, as stated in M.A.901(b), from the date when the last airworthiness review certificate
was issued until the date when the new airworthiness review is performed (this can be up to 90 days
less than 12 months).
M.A.901(o) AMC Airworthiness review
A copy of both the physical survey and document review compliance reports stated above should be
sent to the CAA together with any recommendation issued.
