Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Aircraft Mechanics and Service Technicians

F-35 airframe, powerplant, transmission, and fuel-system inspection and repair experience directly overlaps civilian aircraft maintenance.

How to prepare: Gather records of your military maintenance duties for FAA review against Airframe and Powerplant experience requirements. Certification requires age 18 or older, English proficiency, 18 months of appropriate experience for one rating or 30 months concurrently covering both ratings, or an FAA-approved school or military JSAMTCC training route, plus written, oral, and practical tests; the certificate is not required by FAA for every airline mechanic job, though carriers often require it.

What the civilian work involves
  • Read and interpret maintenance manuals, service bulletins, and other specifications to determine the feasibility and method of repairing or replacing malfunctioning or damaged components.
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.
  • Conduct routine and special inspections as required by regulations.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

F-35 airframe and component inspection and repair experience transfers to aircraft assembly inspection, adjustment, and rework.

How to prepare: Take a hands-on aircraft assembly course covering blueprint interpretation, fastening, and fit-and-alignment checks to bridge from repair work to production assembly.

What the civilian work involves
  • Assemble parts, fittings, or subassemblies on aircraft, using layout tools, hand tools, power tools, or fasteners, such as bolts, screws, rivets, or clamps.
  • Inspect or test installed units, parts, systems, or assemblies for fit, alignment, performance, defects, or compliance with standards, using measuring instruments or test equipment.
  • Adjust, repair, rework, or replace parts or assemblies to ensure proper operation.
