Which EASA regulation would give information about maintenance licenses?

Part 66 of the EASA regulation specifically deals with the requirements and standards for the issuance of maintenance licenses for aircraft engineers. It outlines the qualifications necessary, the types of licenses available (such as LAPL, B1, and B2), and the responsibilities that licensed personnel must uphold regarding aircraft maintenance and safety. This regulation ensures that individuals performing maintenance tasks on aircraft have the required knowledge, skills, and competency to perform their duties effectively.

In contrast, Part 145 pertains to approved maintenance organizations and their authorization to carry out maintenance on aircraft, while Part 147 covers the requirements for training organizations and the approval of training courses for aircraft maintenance personnel. Part 135 relates to operations of commuter and on-demand operations, focusing primarily on the operational side rather than maintenance licensing. Therefore, Part 66 is indeed the regulation that provides comprehensive information about maintenance licenses.
