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

MV-22 airframe, composite, landing gear, and hydraulic system inspection and repair directly overlap civilian aircraft maintenance work.

How to prepare: For positions requiring FAA mechanic certification, ask the FAA to evaluate your military maintenance records for the Airframe rating: the experience route requires 18 months appropriate to one rating or 30 months concurrently covering both Airframe and Powerplant ratings. Applicants must be at least 18, meet English-language requirements, and pass written, oral, and practical tests; an FAA-approved maintenance school or the Joint Service Aviation Maintenance Technician Certification Council course offers an alternative to the experience route.

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.

Aircraft Structure, Surfaces, Rigging, and Systems Assemblers

Aircraft structure and composite repair experience transfers to inspecting and reworking aircraft parts and assemblies in manufacturing.

How to prepare: Practice reading production blueprints and mapping assembly sequences to prepare for the shift from airframe repair to manufacturing work.

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.
