Jobs of aircraft maintenance engineering

All aircraft, with the exception of certain homebuilt and ultralight planes, must carry a valid Certificate of Airworthiness and now an Airworthiness Review Certificate to be legally allowed to fly. In order for this certificate to remain valid, all maintenance on the aircraft must be certified by a licensed AME. All aircraft are maintained periodically in accordance with the Aircraft Maintenance Schedule which comes from the manufacturer of the aircraft and must be approved by local aviation authority. Also, AMEs must rectify defects, which are reported by pilots/cabin crew or found by any maintenance personnel, in accordance with Aircraft Maintenance Manuals (AMM), Illustrated Part Catalogues (IPC), and Wiring Diagram Manuals (WDM). All work performed will be periodically reviewed by Quality Assurance Department (which consists of AMEs as well)if applicable, and with Local Aviation Authority. Also, from time to time, audits are carried out by Quality Assurance Department and Local Aviation Authority on AMEs. Therefore, AMEs carry considerable legal responsibility for ensuring that work has been performed in accordance with the applicable standards of airworthiness
