EASA Part-66

EASA Part-66 is a regulatory framework governing civilian aircraft maintenance licences across the European Union, administered by the European Union Aviation Safety Agency, with adoption linked to harmonisation efforts following the establishment of the Single European Act and subsequent aviation policy under the Treaty of Lisbon. It defines qualification, examination, experience, and authorisation standards that enable licensed personnel to certify maintenance tasks on certificated aircraft operated by entities such as Air France, British Airways, and Lufthansa. The regulation interacts with international instruments including the Chicago Convention and standards promulgated by the International Civil Aviation Organization.

Overview and Scope

The regulation applies to certifying staff responsible for the release to service of aircraft and components used by operators like Ryanair, easyJet, KLM, and Iberia, and by maintenance organisations such as Airbus Engineering, Rolls-Royce plc, and Saab AB. Its scope covers aeroplane and helicopter categories relevant to fleets of Boeing and Airbus types, and extends to maintenance performed under national authorities including EASA member state agencies like the Civil Aviation Authority (United Kingdom) and Direction Générale de l'Aviation Civile. It establishes commonality with international OEM standards from Honeywell International Inc. and GE Aviation while interfacing with training bodies such as CAE Inc. and Lufthansa Technik.

Regulatory Requirements and Privileges

The framework sets out age, medical, competence, and language requirements that align with certifications used by operators like Virgin Atlantic and Turkish Airlines. It grants privileges similar to national licences issued by authorities including the Federal Aviation Administration and the Civil Aviation Safety Authority (Australia), enabling licence holders to issue Certificates of Release to Service for aircraft types listed in approved data from manufacturers such as Bombardier Aerospace and Embraer. Conditions for exercise of privileges reference international safety instruments like the Convention on International Civil Aviation and are subject to oversight by organisations such as European Commission directorates overseeing transport policy.

Licence Categories and Modules

The regulation defines categories A, B1, B2, B3, and C that correspond to occupational roles within maintenance organisations like Airbus SAS MRO units and MTU Aero Engines. Each category is structured into modules reflecting theoretical and practical domains encountered on types produced by Dassault Aviation and ATR. The modular syllabus borrows subject matter relevant to systems developed by Thales Group and Honeywell Aerospace, and examination content aligns with competency frameworks used by training institutions such as Sabena Flight Academy and Oxford Aviation Academy.

Training, Examinations, and Experience

Approved training organisations including CAE Parc Aviation and Aviation Skills Development Centre deliver courses that combine classroom theory, type-specific training, and hands-on experience on platforms like the Airbus A320 family and Boeing 737. Examinations are administered by national authorities and agencies such as EASA and may reference technical manuals from manufacturers including Pratt & Whitney and Safran. Experience requirements for certifying staff are validated through on-the-job training with operators such as Qatar Airways and Emirates, and recorded in logbooks following practices similar to those in Royal Aeronautical Society guidance.

Certification, Renewal, and Transfer

Licences are issued with endorsements for type ratings supported by entries from approved training organisations and verified by competent authorities such as the Irish Aviation Authority and the Civil Aviation Authority of Denmark. Renewal, revalidation, and transfer procedures accommodate cross-border mobility within the European Economic Area and interactions with non-EU systems like the FAA bilateral arrangements. Conversion mechanisms exist for licences from jurisdictions represented by organisations such as the International Air Transport Association when bilateral agreements and safety assessments by EASA permit.

Compliance, Oversight, and Enforcement

National competent authorities including the Swedish Transport Agency and Italian Civil Aviation Authority conduct surveillance, audits, and enforcement actions against maintenance organisations and personnel, sometimes invoking penalties under administrative regimes influenced by decisions of the European Court of Justice. Oversight activities coordinate with major industry stakeholders such as IATA, EUROCONTROL, and OEMs like Boeing to address unsafe practices, continuing airworthiness, and findings from occurrences investigated by bodies including the Bureau of Enquiry and Analysis for Civil Aviation Safety and national accident investigation authorities.
