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

Maintaining and inspecting aircraft pneudraulics systems transfers directly to civilian aircraft hydraulic-system maintenance.

How to prepare: Compile military maintenance records for FAA review of experience toward mechanic ratings. An FAA mechanic certificate is not required for every airline mechanic job, but air carriers often require it for hiring.

What the civilian work involves
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.
  • 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.
Civilian tools and software (examples)
  • Access Software AIRPAX

Maintenance Workers, Machinery

Aircraft pneudraulics maintenance provides a foundation for maintaining industrial machinery, especially equipment with hydraulic or pneumatic systems.

How to prepare: Take a hands-on industrial machinery maintenance course covering machine disassembly, reassembly, and component replacement.

What the civilian work involves
  • Dismantle machines and remove parts for repair, using hand tools, chain falls, jacks, cranes, or hoists.
  • Reassemble machines after the completion of repair or maintenance work.
  • Install, replace, or change machine parts and attachments, according to production specifications.
Civilian tools and software (examples)
  • Computerized maintenance management system software CMMS

Training & Development

Choose credentials for your target role. COOL funding markers describe program listings, not a guarantee of eligibility or funding.

Getting Started

  • Mechanic (Airframe & Powerplant) · Funded · Promotion points · STAR

    Prepare for broader civilian aircraft maintenance work through FAA airframe and powerplant certification.

    Eligibility and preparation: Applicants must be at least 18 and able to read, write, speak, and understand English. The experience route requires 30 months concurrently performing duties appropriate to both ratings; 18 months supports one rating only. Alternatives include graduation from an FAA-approved Aviation Maintenance Technician School or completion of the Joint Service Aviation Maintenance Technician Certification Council course. The FAA evaluates military experience documentation, and applicants must pass written, oral, and practical tests.

    For: Aircraft Mechanics and Service Technicians

  • ASTM NCATT Foreign Object Elimination (FOE)

    Build foreign-object prevention knowledge in housekeeping, tool accountability, and material handling for aircraft maintenance.

    Eligibility and preparation: Open to all individuals regardless of age, career field, training, education, or experience; no AET prerequisite applies.
