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

J-52 experience inspecting, maintaining, testing, and repairing aircraft power plants directly supports civilian aircraft engine maintenance work.

How to prepare: Gather military maintenance records for FAA review of Powerplant rating eligibility rather than assuming engine duties establish experience for both ratings. For the experience route, applicants must be at least 18, meet English-language requirements, document 18 months of appropriate experience for one rating or 30 months concurrently covering both, and pass 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.
  • Maintain repair logs, documenting all preventive and corrective aircraft maintenance.
  • Conduct routine and special inspections as required by regulations.

Notes & Sources

  • An FAA mechanic certificate is not required by regulation for every airline mechanic job, although air carriers often require it for hiring.
