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

Aircraft maintenance, repair and reclamation, quality assurance, and maintenance recordkeeping transfer directly to civilian aircraft maintenance work.

How to prepare: Gather documentary evidence of your military maintenance experience for FAA evaluation toward Airframe and Powerplant ratings, which air carriers often require for hiring but are not required for every airline mechanic job. FAA certification requires age 18 or older, English proficiency, passing knowledge, oral, and practical tests, and either 18 months of appropriate experience for one rating, 30 months concurrently performing duties for both ratings, graduation from an FAA-approved Aviation Maintenance Technician School, or completion of the Joint Service Aviation Maintenance Technician Certification Council training course.

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.
  • Maintain repair logs, documenting all preventive and corrective aircraft maintenance.
  • Conduct routine and special inspections as required by regulations.
Civilian tools and software (examples)
  • Access Software AIRPAX
