What is a B1 Licensed Engineer?

B1 licensed engineers are specialist aircraft mechanics hired to plan, organise and carry out aircraft maintenance checks. These must be in line with an airline’s maintenance schedule, and when particular problems have been identified.

Category B1 licensed engineers are holders of the Part-66 License which certifies aircraft engineers according to the European Aviation Safety Agency’s (EASA) requirements. In the UK, licences are awarded by the Civil Aviation Authority (CAA) which also approves training organisations. Once qualified, B1 licensed engineers can work on aircraft engines and mainframes.



The responsibilities of a B1 licensed engineer includes:

  • Undertaking tasks and projects related to aircraft maintenance
  • Exercising licence/approval in relation to the inspection and everyday processes
  • Ensuring high quality work is completed in relation to aircraft, components and completed documentation
  • Ensuring equipment, facilities and premises are maintained to an acceptable standard
  • Ensuring crews are suitably debriefed to ensure defects are accurately defined and recorded
  • Analysing and interpreting technical information relating to aircraft
  • Reading engineering diagrams and manuals
  • Working closely with other departments to complete project work

B1 licensed engineer jobs typically require individuals to have several years experience of aircraft maintenance and servicing inspection.

Successful applicants will need to be good at trouble-shooting, be in good general health and have strong communications and interpersonal skills. Shift work is common in this role.
