26
To be approved to carry out airworthiness reviews, a CAMO shall have appropriately qualified airworthiness review staff to issue ARCs or make recommendations and if applicable to issue a Permit to Fly
Continuing Airworthiness Management
27
All continuing airworthiness management shall be carried out according to the prescriptions of M.A. Subpart C.
1) Develop and control a maintenance programme for the aircraft managed including any applicable reliability programme;
2) Present the aircraft maintenance programme and its amendments to the competent authority for approval
3) Manage the approval of modifications and repairs
Continuing Airworthiness Management
28

Airworthiness Review CertificateThe ‘Controlled Environment’
• An aircraft in a controlled environment is an aircraft continuously managed by a unique M.A. Subpart G approved continuing airworthiness management organisation in the previous 12 months, and;
• Which has been maintained for the previous 12 months by approved maintenance organisations (Part 145).
43
Airworthiness Review Certificate
• An Airworthiness Review Certificate is valid for 12 months.
• Aircraft in a controlled environment may have the ARC extended twice and only require a full airworthiness review to be carried out every three years.
• Aircraft that are not in a controlled environment, the ARC cannot be extend, a full airworthiness review will be required every year.
• An ARC can only be issued or extended if the aircraft remains airworthy.

30 Days
It is acceptable to anticipate the extension of the ARC by a maximum of 30
days without a loss of continuity of the airworthiness review pattern, which
means that the new expiration date is set up one year after the previous
expiration date. If the ARC is extended after its expiry, the new expiry date
is the same as it would have been if extended at the correct time

Continuing Airworthiness Management Organisation Approval
48
Summary1) Part M Subpart G is an approval to manage aircraft
continuing airworthiness. The privilege can also be extended to include the issue of Airworthiness Review Certificates (or making recommendations to the CAA for the issue of Airworthiness Review Certificates) and the issue of Permits to Fly.
2) All Cat aircraft must be managed by a Subpart G organisation that is part of the AOC.
3) All maintenance must be performed by Part 145 approved organisations
49
Summary
4) The Quality system of the Subpart G must be an integral part of the operators Quality system.
5) An Airworthiness Review Certificate for all aircraft can only be extended by an appropriately approved) Subpart G organisation, when the aircraft has remained within their controlled environment.
