AMC M.A.201 (h)(1) Responsibilities (*)
1.  
An operator only needs to be approved for the management of the continuing air-worthiness of the aircraft listed on its AOC. The approval to carry out airworthiness reviews is optional.

2.  
This approval does not prevent the operator subcontracting certain continuing air-worthiness management tasks to competent persons or organisations. This activity is considered as an integral element of the operator’s M.A. Subpart G approval. The regulatory monitoring is exercised through the operator’s M.A. Subpart G. approval. The contracts should be acceptable to the competent authority.

* see Appendices to Part M -Appendix II to AMC M.A.201 (h) 24
Part-M  AMC M.A.201 (h)(1) Responsibilities
3.  
The accomplishment of continuing airworthiness activities forms an important part of the operator’s responsibility with the operator remaining accountable for satisfac-tory completion irrespective of any contract that may be established.

4.  
Part-M does not provide for organisations to be independently approved to perform continuing airworthiness management tasks on behalf of commercial air transport operators. The approval of such activity is vested in the operator’s air operator’s cer-tificate (AOC). The sub-contracted organisation is considered to perform the continu-ing airworthiness management tasks as an integral part of the operator’s continuing airworthiness management system, irrespective of any other approval held by the subcontractor including a M.A. Subpart G approval.

5.  
The operator is ultimately responsible and therefore accountable for the airworthi-ness of its aircraft. To exercise this responsibility the operator should be satisfied that the actions taken by sub-contracted organisations meet the standards required by

M.A. Subpart G. The operator’s management of such activities should therefore be accomplished
(a)
by active control through direct involvement and/or

(b)
by endorsing the recommendations made by the sub-contracted organisation.

6.  
In order to retain ultimate responsibility the operator should limit sub-contracted tasks to the activities specified below:

(a)
airworthiness directive analysis and planning

(b)
service bulletin analysis

(c)
planning of maintenance

(d)
reliability monitoring, engine health monitoring

(e)
maintenance programme development and amendments

(f)  
any other activities which do not limit the operators responsibilities as agreed by the competent authority.

7.  
The operator’s management controls associated with sub-contracted continuing air-worthiness management tasks should be reflected in the associated written contract and be in accordance with the operator’s policy and procedures defined in his con-tinuing airworthiness management exposition. When such tasks are sub-contracted the operator’s continuing airworthiness management system is considered to be extended to the sub-contracted organisation.

8.  
With the exception of engines and auxiliary power units, contracts would normally be limited to one organisation per aircraft type for any combination of the activities described in Appendix II. Where arrangements are made with more than one organi-sation the operator should demonstrate that adequate co-ordination controls are in place and that the individual responsibilities are clearly defined in related contracts.

9.  
Contracts should not authorise the sub-contracted organisation to sub-contract to other organisations elements of the continuing airworthiness management tasks.

10.
The operator should ensure that any findings arising from the competent authority monitoring of the sub-contracted continuing airworthiness management tasks will be closed to the satisfaction of the competent authority. This provision should be included in the contract.
