AMC M.A.502(b) and (c) Component maintenance    

CAA ORS9 Decision No. 1

M.A.502(b) and (c) allow the performance of certain component maintenance, in accordance with component maintenance data, to maintenance organisations not holding the corresponding B/C rating and to independent certifying staff, subject to the agreement of:

— The CAA when responsible for the oversight of the maintenance organisation (refer to M.1, paragraph 2 for M.A. Subpart F maintenance organisations, or to 145.1 for Part-145 maintenance organisations, or to CAO.1 for Part-CAO maintenance organisations) or,

— The CAA in the case of maintenance performed by independent certifying staff.

This should only be permitted by the CAA in the case of simple component maintenance, where the CAA is satisfied that the certifying staff are appropriately qualified and the proper tooling and facilities are available. It is important to note that for more complex component maintenance, special qualifications may be required and it is not enough with holding a Part-66 aircraft maintenance licence.
