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

Repairing and fabricating aircraft metal, composite, and bonded structural components transfers directly to the structural maintenance side of civilian aircraft repair.

How to prepare: Gather military training and work records for FAA review of experience toward the Airframe rating. Certification is not required for every airline mechanic job, although carriers often require it; applicants must be at least 18, meet English-language requirements, pass written, oral, and practical tests, and qualify through 18 months of appropriate experience, an FAA-approved maintenance school, or the military JSAMTCC 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.

Training & Development

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

Getting Started

  • ASTM NCATT Foreign Object Elimination (FOE)

    Prepare for aircraft maintenance work involving tool accountability, housekeeping, and material handling using the issuer's FOE study guide.

    Eligibility and preparation: No mandatory credential, education, or experience prerequisite; AET certification is not required.

    For: Aircraft Mechanics and Service Technicians

  • Certified Aerospace Technician Core

    Demonstrate aerospace technical knowledge and hands-on skills through written, oral, and practical assessment.

    Eligibility and preparation: Meet one route: active-duty or veteran service in an aeronautical, aviation, aerospace, or engineering specialty or assignment; at least two years of work experience in one of those fields; a relevant college or technical-school degree of at least two years; or an FAA Airframe & Powerplant Certificate.

    For: Aircraft Mechanics and Service Technicians
