Career and Employment Outlook FAA certified maintenance technicians have the important responsibility of keeping aircraft powerplants and their related equipment working safely and efficiently. They service, repair, and overhaul various aircraft components and systems including piston engines, turbine engines, propellers, fuel metering systems and start and ignition systems. Aviation Maintenance Technicians employed by the airlines perform either line maintenance work (for example, routine maintenance, servicing, or emergency repairs at airline terminals) or major repairs and periodic inspections at an airline's overhaul facility. Aviation Maintenance Technicians in general aviation perform maintenance and repairs similar to those performed by airline mechanics, but they may work on small piston-engine or medium sized turbine-powered aircraft, depending on the specialty of the business where employed.
