EUROPEAN UNION COMMISSION REGULATION (EC) NO. 2042/2003
is the base of Aviation Mantenance of a commercial airline. It consists of four annexes:
Annex I Part-M continuing airworthiness requirements
Annex II Part-145 approval of maintenance organisations – commercial air transport and large aircraft
Annex III Part-66 certifying staff – aircraft maintenance licence
Annex IIII Part-147 maintenance training organisation requirements

In the European Union , for all commercial airlines, Aircraft Maintenance Certifying Personnel must be in compliance with part 66 Certifying staff  of the EASA.

There are several Categories:

Category A ( Maintenance Certifying Mechanic): Basic A category License + Task Training for minor tasks (tyre and brake change etc. and up to a weekly check) + Company Certification Authorization for specific Tasks,

Category B1  Maintenance Certifying Technician (Mechanical): Basic B1 category License + Type Training (i.e. Line & Base Maintenance per ATA 104 Level III) + Company Certification Authorization,  permits the holder to issue certificates of release to service (CRS) following maintenance on mechanical and minor avionics and electrical systems.

Category B2  Maintenance Certifying Technician (Avionic):  B2 aircraft maintenance licence + Type Training (i.e. Line & Base Maintenance per ATA 104 Level III) + Company Certification Authorization,  permits the holder to issue certificates of release to service following maintenance on avionic and electrical systems.

Category C (Base Maintenance Certifying Engineer): Basic C category license + Type Training (Line & Base Maintenance i.a.w. ATA 104 Level III for the first Type Rating and ATA 104 Level I training for subsequent Aircraft Types of similar technology, otherwise Level III training) + Company Certification Authorization Category C aircraft maintenance licence permits the holder to issue certificates of release to service (CRS) following base maintenance work on aircraft. 


There are two main aircraft maintenance licences in the world, the  United States, Aircraft Maintenance Technicians (AMT) with their A&P (Part 65 Airframe and Powerplant Mechanics) which are permitted to work under their own certificates and approve their own work for return to service. EASA Part 66 licencensed personnel works under  Part 145 organization, which approves the RTS and the Certifying Technician (with an individual part 66 licence) issues the CRS . 

EASA/JAA differences. The difference between EASA and JAA is that EASA has legal regulatory authority within the European Union (EU). In most of the JAA member countries, their national legislator brings the JARs into a local state law. Many non-European countries are following the EASA/JAR regulations, for instance Canada ,  China, Singapore, the Gulf Emirates and many more. To be able to work throughout the world, it is helpful to have an EASA part 66 licence!  How to get your EASA part 66 B1 or B2 licence? See EASA part 66 / JAR-66 HowToGet!
