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

Inspection, servicing, and repair of UH/AH-1 structures, composites, and hydraulic systems transfer directly to civilian aircraft airframe maintenance.

How to prepare: Ask the FAA to evaluate your military experience records for Airframe rating eligibility before selecting exam preparation. The experience route requires at least 18 months of practical experience appropriate to one rating or 30 months concurrently performing duties appropriate to both Airframe and Powerplant ratings, plus knowledge, oral, and practical tests; applicants must be at least 18 and able to read, write, speak, and understand English, and the verified airframe duties do not establish Powerplant experience.

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.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

Aircraft structural inspection and repair experience provides a foundation for production work involving aircraft assemblies, component fit, and rework.

How to prepare: Practice reading aircraft production blueprints and assembly specifications to bridge from maintenance work to manufacturing sequences.

What the civilian work involves
  • Read blueprints, illustrations, or specifications to determine layouts, sequences of operations, or identities or relationships of parts.
  • 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.
