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

CH-53 experience inspecting, servicing, maintaining, and repairing powerplants, transmissions, drivetrains, fuel systems, flight controls, and rotors directly overlaps aircraft maintenance work.

How to prepare: Assemble documentary evidence of your military maintenance experience for FAA review toward Airframe and Powerplant ratings. FAA certification requires age 18 or older, English proficiency, passing knowledge, oral, and practical tests, and either qualifying practical experience (18 months for one rating or 30 months concurrently for both), 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.

Notes & Sources

  • An FAA mechanic certificate is not a regulatory requirement for every airline mechanic job, although air carriers often require it for hiring.
