AIRCRAFT MAINTENANCE LICENCE

HOW IS THE AML REGULATED?

In order to standardise training and licensing of aircraft technician, the European Aviation Safety Agency, has issued a set of regulations to standardise processes and qualifications in the entire European Union (incl. Switzerland) to get the Aircraft Maintenance Licence (AML). The applicable regulation is known as Part 66.

Part 66 provides, therefore, the requirements for the technical qualification of such personnel, mainly in terms of knowledge and experience. The certification of personnel who meet these requirements is attested by the issuance of an approved EASA Aircraft Maintenance Licence (AML).

As air transport continues to enjoy rapid growth and public attention and awareness to safety has never been as high throughout the entire aviation sector. Training is becoming more vital than ever to ensure sustainability in terms of available resources and applied quality within the industry.

Aviotrace Swiss SA is an EASA Part 147 approved Maintenance Training Organisation and certified to deliver the necessary training to get the Aircraft Maintenance Licence (AML) according to EASA regulation Part 66.

AIRCRAFT MAINTENANCE LICENCE CATEGORIES

The technician or engineer, certified by Aircraft Maintenance Licence, may be specialised according to the maintenance activities he will perform. This specialisation has been standardise by the European Aviation Safety Agency (EASA) through a category segmentation.

The Aircraft Maintenance Licence categories are:

• Category A – Line Maintenance Certifying Mechanic.
• Category B1 – Maintenance Certifying Technician – Mechanical.
• Category B2 – Maintenance Certifying Technician – Avionic.
• Category C – Base Maintenance Certifying Engineer.

In addition, the Aircraft Maintenance Licence categories A and B1 are subdivided into subcategories relative to combinations of airplanes, helicopters, turbine and piston engines as follows:

• A1 and B1.1 Aeroplanes Turbine
• A2 and B1.2 Aeroplanes Piston
• A3 and B1.3 Helicopters Turbine
• A4 and B1.4 Helicopters Piston

Aviotrace Swiss provides the Basic Training for the categories A1, B1.1, B1.3, B2 and C.

Here is a short description of each category and its training and qualification requirements:

 

CATEGORY A1

The Aircraft Maintenance Licence (AML) on entry level Category A1, according to EASA , delivers certification for scheduled line maintenance and basic defect rectification tasks. An AML Category A1 enables maintenance organisations to employ trainees operationally as quickly and efficiently. The upgrade to the more comprehensive AML Category B can be undertaken anytime in accordance with company needs or individual’s decision.

For beginners the ideal training program is a fully approved course lasting 800 hours, delivered as a single course or on modular basis.

Candidates who already have work experience in aircraft maintenance can decide for modular course, which – if completed as single block – is over within a period of 36 days, or can be completed as individual modules delivered at a pace suited to your timeframe.

For more information about fully approved program or modulated courses check our training services

 

CATEGORY B1.1 / B1.3

The Aircraft Maintenance Licence (AML) Category B1.1 (aircraft) and B1.3 (helicopter) according to EASA allows the holder to issue certifications of release to service, following maintenance, including aircraft structure, power plants and mechanical and electrical systems. Authorisation to replace avionic line replaceable units (LRUs) requiring simple tests to prove their serviceability is also permitted.

For beginners the ideal training program is a fully approved course lasting 2,400 hours, delivered as a single course or on modular basis.

Candidates who already have work experience in aircraft maintenance can decide for modular course, which – if completed as single block – is over within a period of 52 days, or can be completed as individual modules delivered at a pace suited to your timeframe.

For more information about fully approved program or modulated courses check our training services

 

CATEGORY B2

The Aircraft Maintenance Licence (AML) Category B2 according to EASA allows the holder to issue certificates of release to service, following maintenance on avionic and electrical systems.

Subsequently, a training to add authorisation capabilities to an existing B2 Licence with the B1 Licence privileges can be undertaken anytime.

For beginners the ideal training program is a fully approved course lasting 2400 hours, delivered as a single course or on modular basis.

Candidates who already have work experience in aircraft maintenance can decide for modular course, which – if completed as single block – is over within a period of 42 days, or can be completed as individual modules delivered at a pace suited to your timeframe.
