Aircraft mechanic (B1)

A B1 technician works on the structure, powerplant and mechanical and electrical systems of aircraft. A Part-66 B1 licence holder may issue certificates of release to service (CRS) within the privileges of the licence and the authorisation granted by the employing organisation.

Tasks

  • Carry out scheduled maintenance checks and inspections.
  • Troubleshoot and rectify defects, replace components.
  • Apply manufacturer documentation (maintenance manuals, task cards).
  • Complete traceability records and, once licensed and authorised, sign the release to service.

B1 subcategories

  • B1.1: turbine-engined aeroplanes
  • B1.2: piston-engined aeroplanes
  • B1.3: turbine-engined helicopters
  • B1.4: piston-engined helicopters

Work environment

Hangars and airport lines, within Part-145 approved maintenance organisations or Part-CAO/Part-M facilities. Shift work, including nights and weekends, is common, with high standards for safety and human factors.

How to get in

Through a vocational aeronautical programme at upper-secondary or post-secondary level, an apprenticeship, or a Part-147 B1 basic training course. Career changers can also prepare the modules through self-study and build the required experience. (In France, these programmes include the CAP and Bac pro โ€” vocational secondary diplomas โ€” and the BTS, a two-year higher technical diploma.)
