M.A.201 Responsibilities
Pre-flight inspection:
Responsibility of Pilot-in-command (or operator in case of CAT: Commercial Air Transport).
Performed by the pilot or another qualified person.No need to be done by approved maintenance organisations or Part-66
certifying staff.
Maintenance of large aircraft and aircraft used in CAT:
Must be performed in Part-145 organisations.
Maintenance of other aircraft:
By Subpart F organisations, by independent Part-66 certifying staff and by the pilot-owner (depending on the type of tasks and as required by M.A.502 and M.A.801(b)).
M.A.201 Responsibilities
Aircraft used in Commercial Air Transport (CAT):
Operator is responsible for continuing airworthiness. Shall be approved as a CAMO (part of the AOC). Shall be approved as Part-145 or contract a Part-145.
Aircraft used in commercial operations other than CAT (if Member State requires a certificate for the operational activities):
Operator is responsible for continuing airworthiness. Shall be approved as CAMO or contract a CAMO. Shall be approved as Subpart F or Part-145 (as applicable for the size of
aircraft) or contract such organisations.
M.A.201 Responsibilities
Private aircraft* (large):
Owner is responsible for continuing airworthiness. Shall contract a CAMO.Maintenance has to be performed in Part-145 (no need for contract).
Private aircraft* (other than large)
Owner is responsible for continuing airworthiness. It is not mandatory to contract a CAMO.Maintenance by Subpart F, independent certifying staff and pilot-owner
(depending on the type of tasks and as required by M.A.502 and M.A.801(b)).
* Private aircraft also include aircraft used for commercial operations other than CAT when the Member State does not require a certificate for the operational activities.
M.A.201 Responsibilities
When contracting a CAMO:
The contract must comply with Appendix I to Part-M.Appendix I describes the responsibilities of the owner and the
responsibilities of the CAMO.
For CAT it is not possible to contract a CAMO. The operator must be approved as a CAMO:
The operator may sub-contract, under its Quality System, some tasks as per AMC to M.A.201(h)1 and its Appendix II.
The subcontracted organisation does not need to be a CAMO.The responsibility for the tasks is always of the operator CAMO.

Ensure that the mass and balance statement is up to date.
M.A.901 Aircraft airworthiness review
An ARC has to be issued with a validity of 1 year in order to ensure the validity of the airworthiness certificate of the aircraft.
May be issued by a CAMO (with privileges), by independent certifying staff (approved by the authority) or by the Competent Authority, depending on the situation.
“Controlled environment” means:
Aircraft managed by CAMO during the previous 12 months, and Maintained only by approved organisations (except for pilot owner
maintenance, when performed by the pilot or by independent certifying staff)
M.A.901 Issuance of the ARC
For aircraft used in CAT and aircraft >2730 Kg MTOM (except balloons):
If the aircraft is in a controlled environment:The CAMO managing the aircraft (if it has airworthiness review privileges) can issue the ARC after performing a full airworthiness review in accordance with M.A.710.
If the aircraft is NOT in a controlled environment or managed by a CAMO without Subpart I privileges:
The ARC will be issued by the Competent Authority based on a recommendation issued by a CAMO with appropriate privileges. The recommendation shall be issued after the CAMO performs a full airworthiness review in accordance with M.A.710.
M.A.901 Issuance of the ARC
For aircraft <2730 Kg MTOM not used in CAT and for balloons:
Any CAMO (if it has airworthiness review privileges) can issue the ARC after performing a full airworthiness review in accordance with M.A.710 (regardless of whether the aircraft is in a controlled environment or not and regardless of whether the CAMO manages the aircraft or not).
For ELA1 aircraft (privately used):
The ARC may also be issued by the Competent Authority based on a recommendation issued by independent certifying staff (approved by the authority). The recommendation shall be issued after the certifying staff performs a full airworthiness review in accordance with M.A.710.
M.A.901 Issuance of the ARC
If there is a potential safety threat, the authority shall perform the airworthiness review and issue the ARC themselves.
The authority may also perform the airworthiness review and issue the ARC themselves in the following cases:
When the aircraft is managed by a CAMO located outside the EU (since they cannot have privileges for airworthiness review).
When the owner requests it for balloons and aircraft <2730Kg MTOM.
M.A.901 Extension of the ARC
Extension of the ARC
The CAMO managing the aircraft may, if the aircraft is in a controlled environment, extend twice (1 year each time) an ARC which has been issued by a CAMO or by the Competent Authority.
There is no need for the CAMO to have airworthiness review privileges since the ARC is extended without performing an airworthiness review.
Subpart G: Airworthiness Review
M.A.710 Airworthiness Review
It is applicable to airworthiness reviews performed by a CAMO, by independent certifying staff and by the Competent Authority.
It includes a documental review of the aircraft records and a physical survey of the aircraft.
The CAMO may advance it up to 90 days (without losing the continuity pattern) to allow the physical survey to take place during a maintenance check.
Airworthiness reviews cannot be sub-contracted.
A copy of any ARC issued or extended by the CAMO shall be sent to the Member State of Registry within 10 days.
