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.

Avionics Technicians

Intermediate-level testing and repair of aircraft electrical and flight control components, modules, and circuit boards directly overlaps avionics component maintenance.

How to prepare: Prepare a component-repair work sample describing the inspection, test, repair, and verification steps, using only information cleared for public release.

What the civilian work involves
  • Test and troubleshoot instruments, components, and assemblies, using circuit testers, oscilloscopes, or voltmeters.
  • Adjust, repair, or replace malfunctioning components or assemblies, using hand tools or soldering irons.
  • Keep records of maintenance and repair work.
Civilian tools and software (examples)
  • Microsoft Excel

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Inspecting, testing, and repairing aircraft electrical assemblies and circuit boards provides a component-level repair foundation for commercial and industrial electronics.

How to prepare: Complete a hands-on industrial equipment troubleshooting course to practice fault diagnosis and functional testing outside aircraft systems.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
