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

F-404 power plant inspection, maintenance, testing, and complete repair transfer directly to civilian aircraft engine maintenance.

How to prepare: Compile military maintenance records for FAA evaluation toward the Powerplant rating. Applicants must be at least 18, meet English-language requirements, document 18 months of appropriate practical experience or complete an accepted FAA-approved school or military JSAMTCC training route, and pass knowledge, oral, and practical tests; the certificate is not required for every airline mechanic job, though air carriers often require it for hiring.

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.
