Aircraft Mechanics I must have a combination of experience to repair engines, sheet metal, structural, hydraulic, electrical, power train and general mechanical maintenance of moderate difficulty, required to meet the assigned missions. Makes repairs to aircraft and follows direction of higher graded workers. The Aircraft Mechanic l troubleshoots malfunctions in aircraft structure, landing gear, flight surfaces and controls, anti-icing, pneudraulic, engines, auxiliary power unit, and ventilation and heating systems. This mechanic repairs, replaces, and rebuilds aircraft structures, such as wings and fuselage, and functional components including rigging, surface controls, and plumbing and hydraulic units, using hand tools, power tools, machines, and equipment such as shears, sheet metal brake, welding equipment, rivet gun, and drills. This worker reads and interprets manufacturers' and airlines’ maintenance manuals, service bulletins, technical data, engineering data, and other specifications to determine feasibility and method of repairing or replacing malfunctioning or damaged components. Work involves replacing or repairing worn or damaged components, such as carburetors, alternators, magnetos, fuel controls, fuel pumps, oil pumps, and engine mounted gearboxes, and compressor bleed valves using hand tools, gauges, and testing equipment; removing engine from aircraft, using hoist or forklift truck, disassembling and inspecting parts for wear, cracks, security, or other defects, and repairing or replacing defective engine parts and reassembles and installs engine in aircraft. Job duties require that this mechanic adjusts, repairs, or replaces electrical wiring system and aircraft accessories, performs preflight, thru-flight, and postflight maintenance inspections, performs miscellaneous duties to service aircraft, including flushing crankcase, cleaning screens and filters, greasing moving parts, and checking brakes. Participate in jacking and towing of aircraft, enters in the maintenance records description of the work performed and verifies the work was performed satisfactorily, service engines and airframe components at line station making repairs, short of overhaul, required to keep aircraft in safe operating condition, specialize in work, repair and modification of structural, precision, and functional spare parts and assemblies, and specialize in engine repair. May be required to be licensed by Federal Aviation Administration. May require specialization in sheet-metal, electric work, avionics or other aircraft systems related disciplines.
- Perform 100-hour, progressive, isochronal, phase, periodic, and other hourly or calendar inspections
- Examine reciprocating engines for cracked cylinders and oil leaks
- Listen to operating engine to detect and diagnose malfunctions, such as sticking or burnt valves, inspects jet engines and components for cracks, corrosion, foreign object damage, burned areas, distortions, security, warping, wear, and missing segments
- Inspect jet engine turbine blades to detect cracks, distortion, corrosion, burn-out, security, or breaks
- Test engine operation, using testing equipment, such as ignition analyzer, compression checker, distributor timer, ammeter, and jet calibration (jetcal) tester, to locate source of malfunction
