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, servicing, maintaining, and repairing UH/AH-1 powerplants, transmissions, drivetrains, fuel systems, flight controls, and rotors directly overlaps civilian aircraft maintenance.

How to prepare: Gather military maintenance records for an FAA review of experience toward Airframe and Powerplant certification. Applicants must be at least 18 and able to read, write, speak, and understand English; both ratings require 30 months of concurrent appropriate experience or an eligible FAA-approved school or military certification-course route, followed by knowledge, 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.
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.
  • Conduct routine and special inspections as required by regulations.

Notes & Sources

  • Air carriers often require FAA mechanic certification for hiring, although it is not an FAA regulatory requirement for every airline mechanic job.
