Scope	Continuing airworthiness of non-complex and complex aircraft

EASA Part-M is a regulatory framework issued by the European Union Aviation Safety Agency to govern the continuing airworthiness of aircraft and components within the European Union and associated states. It interacts with other regulatory instruments from International Civil Aviation Organization, European Commission, and national aviation authorities such as the Civil Aviation Authority (United Kingdom), Direction Générale de l'Aviation Civile, and Luftfahrt-Bundesamt. The rule set defines obligations for aircraft owners, operators, maintenance organisations, and continuing airworthiness managers across civil aviation sectors including commercial air transport, aerial work, and general aviation.

Overview

Part-M establishes standards for airworthiness tasks, aircraft release to service, and recordkeeping comparable to frameworks used by Federal Aviation Administration, Transport Canada Civil Aviation, and Civil Aviation Administration of China. It complements operational rules found in EASA Part-OPS, EASA Part-CAMO, and maintenance organisational rules in EASA Part-145. Part-M interfaces with international instruments such as Chicago Convention and regional agreements like the European Civil Aviation Conference protocols. Its provisions are applied by national competent authorities including Agência Nacional de Aviação Civil (Brazil) when bilateral arrangements reference EASA standards.

Applicability and Scope

Part-M applies to the continuing airworthiness of aircraft registered in European Union Member States, European Free Trade Association participants, and third countries that have accepted EASA delegated responsibilities. Applicability covers categories ranging from large aeroplanes certificated under Joint Aviation Authorities transitional rules to small private aeroplanes operated under ICAO Annex 8 equivalence. It specifies when requirements in EASA Part-ML or EASA Part-CAMO take precedence and defines interfaces with airworthiness certification instruments like EASA Supplemental Type Certificate processes and Noise and Emissions Certification regimes. National exemptions and implementation measures often involve coordination with entities such as European Commission Directorate-General for Mobility and Transport and state civil aviation authorities like Ente Nazionale per l'Aviazione Civile.

Continuing Airworthiness Requirements

The rule mandates programme-based continuing airworthiness including maintenance programmes, inspection schedules, and life-limited parts management drawn from type certificates and instructions for continued airworthiness issued by manufacturers including Airbus, Boeing, ATR (tecnam), and Bombardier Aerospace. Part-M requires occurrence reporting consistent with European Union Aviation Safety Agency safety promotion and coordination with European Aviation Safety Programme networks. It prescribes mandatory actions for service bulletins and airworthiness directives issued by authorities such as EASA, Federal Aviation Administration, and national agencies like Dirección General de Aeronáutica Civil (Mexico). The framework sets standards for component traceability and documentation aligned with practices of organisations like International Air Transport Association and Aviation Suppliers Association.

Maintenance Organisation Responsibilities

Maintenance organisations must comply with interfaces between Part-M continuing airworthiness management and Part-145 approved maintenance providers such as facilities accredited by European Union Member State competent authorities. Responsibilities include release to service certificates, deferred defect control, and management of unairworthy conditions in coordination with design approval holders such as Dassault Aviation, Embraer, and Saab AB. Organisations must implement quality systems reflecting standards promoted by European Committee for Standardization and aviation industry groups like Aerospace Industries Association and International Civil Aviation Organization annexes. Interaction with maintenance training bodies recognised by authorities like European Aviation Safety Agency ensures personnel competency for tasks such as non-destructive testing and avionics troubleshooting.

Airworthiness Review and Continuing Airworthiness Management Organisations (CAMO)

Part-M sets out requirements for airworthiness reviews carried out by qualified persons or organisations approved as Continuing Airworthiness Management Organisations (CAMO). CAMOs hold responsibilities for establishing maintenance programmes, monitoring reliability, and keeping records consistent with instructions from type certificate holders such as Rolls-Royce Holdings and General Electric Aviation. Airworthiness review certificates are administered in cooperation with national authorities like Swedish Transport Agency, Bundesamt für Zivilluftfahrt, and Dirección General de Aviación Civil (Spain). CAMO oversight often aligns with industry initiatives promoted by groups such as European Regions Airline Association and Association of European Airline Pilots.

Compliance and Enforcement

Enforcement of Part-M rests with national competent authorities and coordinated oversight by European Union Aviation Safety Agency through inspections, occurrence investigations, and administrative actions including fines, grounding, or certificate suspension. Compliance mechanisms mirror practices used by Federal Aviation Administration's certificate actions and enforcement programs and draw on investigative cooperation with entities like European Union Agency for Law Enforcement Cooperation when fraud or deliberate non-compliance arises. Harmonisation efforts involve stakeholder consultations with organisations such as European Transport Workers' Federation and industry trade bodies like International Air Transport Association.

Historical Development and Revisions

Part-M emerged from the consolidation of earlier European regulatory instruments including the Joint Aviation Authorities syllabi and transitional measures following the establishment of the European Aviation Safety Agency in 2003. Major revisions and amendment packages were promulgated alongside related rulemaking such as the introduction of EASA Basic Regulation updates and the creation of Part-CAMO and Part-ML for simplification. Revisions responded to safety recommendations from investigations involving organisations like European Union Aviation Safety Agency safety analysis units and incidents examined by bodies such as the Air Accidents Investigation Branch, Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile, and NTSB.
