AMC1 CAMO.A.315(c) Continuing airworthiness management    

CAA ORS9 Decision No. 1

(a) As provided for in M.A.201 or ML.A.201, when the operator is approved as a CAMO, or when the operator/owner contracts a CAMO, this CAMO is in charge of the continuing airworthiness management and this includes the tasks specified:

— for Part-M aircraft, in M.A.301 points (b), (c), (e), (f), (g) and (h);

— for Part-ML aircraft, in ML.A.301 points (b), (c), (d) and (e).

If the CAMO does not hold the appropriate maintenance organisation approval (Part-M Subpart F, Part-CAO or a Part-145 approval), then the CAMO should conclude a contract with the appropriate organisation(s).

(b) The CAMO bears the responsibility for the airworthy condition of the aircraft for which it performs the continuing airworthiness management. Thus, it should be satisfied before the intended flight that all required maintenance has been properly carried out.

(c) The CAMO should agree with the operator on the process to select a maintenance organisation before concluding any contract with a maintenance organisation.

(d) The fact that the CAMO has contracted a maintenance organisation should not prevent it from checking at the maintenance facilities on any aspect of the contracted work to fulfil its responsibility for the airworthiness of the aircraft.

(e) The contract between the CAMO and the maintenance organisation(s) should specify in detail the responsibilities and the work to be performed by each party.

(f) Both the specification of work and the assignment of responsibilities should be clear, unambiguous and sufficiently detailed to ensure that no misunderstanding arises between the parties concerned that could result in a situation where work that has an effect on the airworthiness or serviceability of aircraft is not or will not be properly performed.

(g) Special attention should be paid to procedures and responsibilities to ensure that all maintenance work is performed, service bulletins are analysed and decisions are taken on their accomplishment, airworthiness directives are accomplished on time and that all work, including non-mandatory modifications, is carried out to approved data and to the latest standards.

(h) Appendix IV to AMC1 CAMO.A.315(c) gives further details on the subject.
