  • Reassemble engines following repair or inspection and reinstall engines in aircraft.
  • Read and interpret pilots' descriptions of problems to diagnose causes.
  • Modify aircraft structures, space vehicles, systems, or components, following drawings, schematics, charts, engineering orders, and technical publications.
  • Install and align repaired or replacement parts for subsequent riveting or welding, using clamps and wrenches.
  • Locate and mark dimensions and reference lines on defective or replacement parts, using templates, scribes, compasses, and steel rules.
  • Clean, strip, prime, and sand structural surfaces and materials to prepare them for bonding.
  • Service and maintain aircraft and related apparatus by performing activities such as flushing crankcases, cleaning screens, and lubricating moving parts.

  • Clean engines, sediment bulk and screens, and carburetors, adjusting carburetor float levels.
  • Prepare and paint aircraft surfaces.
  • Spread plastic film over areas to be repaired to prevent damage to surrounding areas.
  • Check for corrosion, distortion, and invisible cracks in the fuselage, wings, and tail, using x-ray and magnetic inspection equipment.
  • Disassemble engines and inspect parts, such as turbine blades and cylinders, for corrosion, wear, warping, cracks, and leaks, using precision measuring instruments, x-rays, and magnetic inspection equipment.
  • Determine repair limits for engine hot section parts.
  • Cure bonded structures, using portable or stationary curing equipment.
  • Listen to operating engines to detect and diagnose malfunctions such as sticking or burned valves.
  • Accompany aircraft on flights to make in-flight adjustments and corrections.
  • Remove, inspect, repair, and install in-flight refueling stores and external fuel tanks.
