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, overhauling, installing, and testing aircraft hydraulic and in-flight refueling components transfers directly to aircraft component maintenance.

How to prepare: Gather military maintenance records for an FAA review of experience toward the Airframe rating. FAA certification requires age 18, English proficiency, written, oral, and practical tests, plus 18 months of appropriate experience for one rating or 30 months concurrently covering both, or an FAA-approved school or military certification-course route; air carriers often require certification even though it is not required for every airline mechanic job.

What the civilian work involves
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.
  • Read and interpret maintenance manuals, service bulletins, and other specifications to determine the feasibility and method of repairing or replacing malfunctioning or damaged components.
  • Maintain repair logs, documenting all preventive and corrective aircraft maintenance.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

Installing, adjusting, inspecting, and testing aircraft hydraulic components provides a foundation for aircraft systems assembly and rework.

How to prepare: Practice reading aircraft production blueprints and assembly specifications, focusing on hydraulic-system installation and inspection 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.

Training & Development

Choose credentials for your target role. COOL funding markers describe program listings, not a guarantee of eligibility or funding.

Getting Started

  • ASTM NCATT Foreign Object Elimination (FOE)

    Build foreign-object prevention knowledge in housekeeping, tool accountability, and material handling for aircraft maintenance and assembly work.

    Eligibility and preparation: The exam is open regardless of age, career field, training, education, or experience; AET certification is not required.
