A Mechanic performs all required maintenance and inspections of aircraft engines, landing gear, pressurized sections, instruments, and accessories (e.g., pumps, valves, brakes, air conditioning), including parts replacement and maintenance. With larger and more complex planes, the Mechanic will retrieve valuable diagnostic data from the electronic boxes and consoles that track a plane's central or basic functions. They also maintain all records related to maintenance performed on each aircraft. The inspection schedule for each aircraft is based on one or any combination of factors: the number of flight hours that the aircraft has accumulated, the length of time (in days) that have elapsed since its last inspection, and the cycles of operation.
When examining an engine in all plane types, the Mechanic will stand on a scaffold or ladder, or use a lift to reach a special door/opening that allows direct access to the engine in order to examine, repair, or remove it completely. If needed, the Mechanic will disassemble the engine, and with specialized tools and instruments, evaluate various components while looking for any wear or corrosion. X-ray and magnetic inspection equipment may also be used to detect any unnoticeable or invisible cracks. Once the Mechanic's evaluation is completed, they will replace or repair any deteriorated or defective parts.
A Mechanic also evaluates and services various other parts of an aircraft, including: repairing sheet metal or composite surfaces measuring control cable tension looking for and evaluating corrosion, distortion, and cracks in
