11.
The sub-contracted organisation should agree to notify the respective operators of any changes affecting the contracts as soon as practical. The operator should then inform its competent authority. Failure to do so may invalidate the competent authority acceptance of the contract.

Appendix II provides information on the sub-contracting of continuing airworthiness management tasks.
13.
The operator should only sub contract to organisations which are specified by the competent authority on the AOC or EASA Form 14 as applicable.
AMC M.A.201 (h)(2) Responsibilities
1. The requirement is intended to provide for the possibility of the following three alternative options:
(a)
an operator to be approved in accordance with Part-145 to carry out all mainte-nance of the aircraft and components;
(b)
an operator to be approved in accordance with Part-145 to carry out some of the maintenance of the aircraft and components. This, at minimum, could be limited line maintenance but may be considerably more but still short of option (a);
(c)
An operator not approved in accordance with Part-145 to carry out any mainte-nance.
2. An operator or prospective operator may apply for any one of these options but it will be for the competent authority to determine which option may be accepted in each particular case.
2.1 To make this determination the competent authority will apply the primary criteria of relevant operator experience if carrying out some or all maintenance on comparable aircraft. Therefore where an operator applies for option (a) – all maintenance – the competent authority will need to be satisfied that the opera-tor has sufficient experience of carrying out all maintenance on a comparable type. For example, assuming that the experience is judged satisfactory, then it is reasonable from the maintenance viewpoint to add a different wide bodied air-craft to an existing wide bodied fleet. If the experience is not satisfactory or too limited the competent authority may choose either to require more experienced management and/or more experienced release to service staff or may refuse to accept the new wide bodied aircraft if extra experienced staff cannot be found. Option (b) or (c) may be possible alternatives.
2.2 Where an operator applies for option (b) – some maintenance or the competent authority has been unable to accept an application for option (a) – then satis-factory experience is again the key but in this case the satisfactory experience is related to the reduced maintenance of this option. If the experience is not satisfactory or too limited the competent authority may choose to require more experienced staff or may refuse to accept the application if such staff cannot be found. Option (c) may be the possible alternative. Option (c) accepts that the operator either does not have satisfactory experience or has only limited experi-ence of some maintenance.
2.3 The competent authority will require an operator to enter into a contract with an appropriately approved Part-145 organisation except in those cases where the competent authority believes that it is possible to obtain sufficient satisfactorily experienced staff to provide the minimal maintenance support for option (b), in which case option (b) would apply.
2.4 In respect of this paragraph, ‘experience’ means staff who have proven evidence that they were directly involved with at least line maintenance of similar aircraft types for not less than 12 months. Such experience should be demonstrated to be satisfactory. An operator is required to have enough personnel meeting the requirement of M.A.706 to manage the maintenance responsibility whichever option is used.
