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, maintaining, testing, and repairing aircraft engines and propellers transfers directly to engine-focused aircraft maintenance work.

How to prepare: Assemble your engine-maintenance records for FAA review toward the Powerplant rating rather than assuming eligibility for both Powerplant and Airframe ratings. FAA certification is not required for every airline mechanic job, although air carriers often require it for hiring.

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.

Aerospace Engineering and Operations Technologists and Technicians

Testing propulsion systems and maintaining engine ground support equipment provides a foundation for aerospace test-equipment and test-operations work.

How to prepare: Take a practical course in test instrumentation and data acquisition to bridge from maintenance testing to engineering test setups and data interpretation.

What the civilian work involves
  • Identify required data, data acquisition plans, and test parameters, setting up equipment to conform to these specifications.
  • Inspect, diagnose, maintain, and operate test setups and equipment to detect malfunctions.
  • Record and interpret test data on parts, assemblies, and mechanisms.

Training & Development

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

Getting Started

  • Mechanic (Powerplant)

    Earn the FAA rating aligned with documented aircraft-engine maintenance experience.

    Eligibility and preparation: Applicants must be at least 18 and able to read, write, speak, and understand English. The experience route requires at least 18 months of practical experience appropriate to the Powerplant rating; alternatives include graduation from an FAA-approved Aviation Maintenance Technician School or completion of the Joint Service Aviation Maintenance Technician Certification Council course. Knowledge, oral, and practical tests must be passed.

    For: Aircraft Mechanics and Service Technicians

  • Certified Aerospace Technician Core

    Demonstrate foundational aerospace technical knowledge and practical skills for a move into test operations.

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