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

Inspecting, testing, maintaining, and completely repairing F-402 aircraft power plants and their systems directly supports civilian aircraft engine maintenance work.

How to prepare: Gather documentary evidence of your military maintenance experience for FAA review to determine whether it supports the Powerplant rating or both Airframe and Powerplant ratings.

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

  • FAA mechanic certification requires age 18 or older, English proficiency, and passing knowledge, oral, and practical tests. The experience route requires 18 months appropriate to one rating or 30 months concurrently appropriate to both; FAA-approved school graduation or completion of the military JSAMTCC course provides an alternative route. The FAA evaluates military experience documentation. Certification is not required by FAA regulation for every airline mechanic job, though air carriers often require it for hiring.
