Introducing EASA Part 66 AMEL Categories

www.easaonline.com presents the different categories available within the EASA Part 66 licence 

On the basis of the Maintenance Engineers License, together with satisfactory demonstration of competency and knowledge of organizational procedures the personal authorization document is issued by an approved Part-145 organization. 

Note - Whilst Category A is not maybe the best choice to sit for your licence, clearly as it is incorporated within the B1 licence it can be of significant benefit to allow the B1 Engineer to be task trained on multiple aircraft. 

A Category “A” License holder may only certify his (or her) own work and cannot certify the work of other individuals. 

The Category “A” based approval is a task based approval which is restricted to the mechanical systems, although simple and limited avionic tasks as for example which may be found on a daily inspection or a weekly check, can be included with the approval of the Competent Authority.

(b) Categories A and B1 are subdivided into subcategories relative to combinations of Aeroplanes, helicopters, turbine and piston engines.

These subcategories are: 

— A1 and B1.1 Aeroplanes Turbine 

— A2 and B1.2 Aeroplanes Piston

— A3 and B1.3 Helicopters Turbine

— A4 and B1.4 Helicopters Piston

 

Category “B1” & “B2”

The Basic “B1” & “B2” Licenses alone, do not convey certification rights, an aircraft type rating needs to be added to the License, prior to the holder gaining an authorization. (but note that a B1 License (only) includes the privileges of a Category “A” License. So it is possible for the BI not holding a Type rating to have limited approval on a particular Aircraft Type (using the privilege of the “A” licence ! 

On the basis of the “B1” And “B2”  Maintenance Engineers License, together with Type Training and Rating plus satisfactory demonstration of required practical experience plus competency and knowledge of organizational procedures the personal authorization document is issued by an approved Part-145 organization. 

The privileges of a “B1” typically include Certification privileges on aircraft structures, power plant, mechanical systems and electrical systems. Including replacement of avionic line replaceable units (LRUs) requiring simple tests to prove serviceability. Either by the use of BITE (Built in Test Equipment). 

The privileges of “B2” typically include certification privileges on Aircraft Electrical and Avionic systems. 

Category B3 is applicable to piston-engine non-pressurized  aeroplanes of 2 000 kg MTOM and below. A category B3 aircraft maintenance License shall permit the holder to issue certificates of release to service and to act as B3 support staff for:

Maintenance performed on aeroplane structure, powerplant and mechanical and electrical systems,

— work on avionic systems requiring only simple tests to prove their serviceability and not requiring troubleshooting.

 

Category C

The Basic C License alone, The Basic License alone, does not convey certification Rights, I An aircraft type rating needs to be added to the License prior to the holder gaining an authorization.

  “C” Licensed Rating is able to certify Base Maintenance which consists of large checks – usually “C” checks and above. A single signature releases the aircraft from Base Maintenance check which may in fact contain some 1000’s of tasks. During base maintenance the individual tasks which are sign for are not in fact certifications merely a record of who has completed the task. Normally the company will identify what people are allowed to sign for during base maintenance and it will be demonstrated on the individuals approval certificate.
