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

Troubleshooting, inspecting, and repairing aircraft fuel tanks and associated hardware transfers directly to aircraft maintenance work.

How to prepare: Compile records of your maintenance duties and duration for FAA review of experience toward an Airframe or Powerplant rating. Where certification is required for hiring, FAA eligibility includes age 18, English proficiency, appropriate experience of 18 months for one rating or 30 months concurrently for both, or an approved school or qualifying military training route, plus written, oral, and practical tests.

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.
  • Maintain repair logs, documenting all preventive and corrective aircraft maintenance.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

Removing, installing, and inspecting aircraft fuel systems and their hardware provides a practical foundation for aircraft systems assembly and rework.

How to prepare: Practice reading aircraft assembly blueprints and specifications to identify component relationships and installation sequences.

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.
