EASA Part-66 B1 & B2 License Training
Structured examination guidance for aircraft maintenance technicians working toward EASA Part-66 B1.1 mechanical or B2 avionics licensing.
Build the technical foundation for an EASA maintenance license.
EASA Part-66 training is the theoretical qualification pathway required for an EASA Aircraft Maintenance License. It develops the knowledge aircraft maintenance technicians need to work safely and competently in regulated maintenance environments.
At Aero Mentor 66, our Part-66 examination guidance covers the core modules defined under EASA Part-66. The programme combines structured study material, instructor-led clarification and examination preparation so trainees can progress with a clear plan.
The training supports future certification pathways and helps technicians move toward B1.1 mechanical and B2 avionics responsibilities and EASA Aircraft Maintenance License requirements.
What the training covers
- Aircraft aerodynamics and structures
- Turbine engines and propulsion systems
- Electrical and electronic systems
- Digital techniques and instrument systems
- Maintenance practices and materials
- Aviation legislation, human factors and safety
The Part-66 license is divided into categories, with structured training pathways available for both mechanical and avionics disciplines.
Categories offered
Turbine aeroplane systems, structures, engines and mechanical maintenance.
Aircraft electrical systems, digital techniques, instrumentation and navigation.
An integrated pathway covering both mechanical and avionics competencies.
