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-47 inspections, mechanical repairs, subsystem replacement, and maintenance records directly overlap with civilian aircraft maintenance work.

How to prepare: Gather maintenance records and documentation of your military duties for an FAA evaluation of experience toward Airframe and Powerplant ratings. Air carriers often require the mechanic certificate for hiring, although it is not an FAA requirement for every airline mechanic job.

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.

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

    Earn both FAA mechanic ratings to support entry into civilian aircraft maintenance.

    Eligibility and preparation: Applicants must be at least 18 and able to read, write, speak, and understand English. The experience route for both ratings requires 30 months concurrently performing duties appropriate to both; alternatives include graduation from an FAA-approved Aviation Maintenance Technician School or completion of the Joint Service Aviation Maintenance Technician Certification Council training course. Knowledge, oral, and practical tests are required.
