Component Maintenance

                                  M.A.502 Component Maintenance
              (a) The maintenance of components shall be performed by maintenance
organisations appropriately approved in accordance with Section A, Subpart F of CAR M or with CAR 145.
             (b) By derogation from paragraph (a), maintenance of a component in accordance
with aircraft maintenance data or, if agreed by DGCA, in accordance with component maintenance data, may be performed by an A rated organisation approved in accordance with Section A, Subpart F of CAR-M or CAR 145 as well as by certifying staff referred to in point M.A. 801(b)2 only whilst such components are fitted to the aircraft. Nevertheless, such organisation or certifying staff may temporarily remove this component for maintenance, in order to improve access to the component, except when such removal generates the need for additional maintenance not eligible for the provisions of this paragraph. Component
maintenance performed in accordance with this paragraph is not eligible for the issuance of a CA Form 1 and shall be subject to the aircraft release requirements provided for in point M.A.801.
           (c) By derogation from paragraph (a), maintenance of an engine / Auxiliary Power
Unit (APU) component in accordance with engine/APU maintenance data or, if agreed by DGCA, in accordance with component maintenance data, may be performed by a B rated organisation approved in accordance with Section A, Subpart F of CAR-M or CAR 145 only whilst such components are fitted to the engine/APU. Nevertheless, such B rated organisation may temporarily remove this component for maintenance, in order to improve access to the component, except when such removal generates the need for additional maintenance not eligible for the provisions of this paragraph.
         (d) By derogation from paragraph (a) and point M.A.801(b)2, maintenance of a
component while installed or temporarily removed from a Light aircraft not used in
commercial air transport and performed in accordance with component maintenance data, may be performed by certifying staff referred to in point M.A.801(b)2, except for:
1. overhaul of components other than engines and propellers, and;
2. overhaul of engines and propellers for aircraft other than CS-VLA,
CS-22 and LSA. Component maintenance performed in accordance with paragraph (d) is not eligible for the issuance of a CA Form 1 and shall be subject to the aircraft
release requirements provided for in point M.A.801.
                                  AMC M.A.502 Component maintenance
            Component removal from and installation on an aircraft is considered to be aircraft
maintenance and not component maintenance. As a consequence, M.A.502 requirements do not apply to this case.
                                AMC M.A.502(b) and (c) Component maintenance
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: DGCA This should only be permitted by the DGCA in the case of simple component
maintenance, where the DGCA 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 CAR-66 aircraft maintenance licence.
