  • Repair or replace wiring, connectors, antennas, sensors, and electronic modules
  • Perform functional tests and calibrations after maintenance or upgrades
  • Update software and configuration settings for aircraft electronic systems
  • Document work, test results, and parts used to meet safety rules
  • Coordinate with mechanics, pilots, and inspectors to confirm issues and fixes

A day in the life

  1. Review work orders, manuals, and safety steps before touching the aircraft
  2. Inspect wiring and components, then run tests to find the root cause
  3. Repair, rewire, or swap units, then retest until results meet limits
