Part 66 Cat B Program

EASA Part 66 Category B program permits, subject to the exact subcategory, the holder to issue Certifications of Release to Service following maintenance, including aircraft structure, power plants, mechanical, electrical and avionics systems.


The Aircraft Maintenance Engineer (AMEL) certification is specialized licensing program for servicing and maintenance of Aircrafts in terms of
maintenance, inspection, repair or their modifications.

Attending the Aircraft Maintenance Engineering Program (AME) at a Center of Aviation (CoA) is recommended and High school
students/University graduates are encouraged to enroll.

This program is developed by EASA to impart knowledge and skills in maintenance of both large and small size Aircrafts and is subdivided in following sub-categories.

  • Cat B1.1 Gas Turbine Aeroplane
  • Cat B1.2 Piston Engine Aeroplane
  • Cat B 1.3 Gas Turbine Helicopter
  • Cat B1.2 Piston Engine Helicopter
  • Cat B2 Avionics
  • Cat B3 Aeroplanes below 2000 KGs

Aircraft Maintenance Engineering licensing Course is a 3 years course divided into 9 sessions. Each session is of around 3.5 months ending with European Aviation Safety Agency (EASA) Part 66 exams conducted by AERO-Bildung GMBH, Germany.

The course consists of Theoretical and Practical training in on-site workshops. The 3 years training program prepares students to meet all challenges of the aviation engineering environment.


This program is offered in partnership with AERO-Bildung GMBH Germany (EASA Approved Part 147 organisation) and meets the basic modular training requirements for the Aircraft Maintenance Engineer’s license.

After successful completion of this program and the required work experience, apprentices qualify to write an exam in Aircraft Maintenance Regulations to acquire an Aircraft Maintenance Engineer’s license.

Course Outline

The B1 license is a mechanical based license and permits the holder to issue certificates of release to service following line maintenance, including aircraft structure, power plants and mechanical systems of an aircraft. Below is the brief detail on the EASA Part 66 Modules studied during the course.

M1. Mathematics
The mathematics module, required for all licenses, starts with very simple topics to build your confidence before moving on to more complicated topics
of the syllabus. The module covers three chapters, Arithmetic, Algebra and Geometry. Although the chapters are quite large they have been broken down
to enable you to study a small section at a time. This is an ideal module to begin studying for your license as it will ease you into studying and build up
your mathematical skills to meet any requirements in further modules.

M2. Physics
The physics module is required for all licenses and includes five chapters matter, mechanics, thermodynamics, optics (light) and wave motion & sound.
The basic physics contained in this module is applied in more detail in more specialized modules. As well as learning laws and equations this involves
applying theoretical concepts to real life situations making it the ideal companion, or follow-on, for the mathematics module.

M3. Electrical Fundamentals
This module is required for all licenses and covers the spectrum of aircraft’s power generation that includes electricity, magnetism, generators,
transformers and motors. This module provides a basis for electrical modules required for the license, especially for module 4: Electronic fundamentals.

M4. Electronic Fundamentals
This module is required for B1 and B2 licenses only. It comprises of the basic avionics of the aircraft that includes semiconductors, printed circuit boards
and servomechanisms. Although this module is to be studied by B1 and B2 but there is substantially more work for the B2 license at a higher level than
for B1. This module provides an excellent follow on from module 3: Electrical fundamentals.

M5. Digital Techniques/Electronic Displays
The modern airlines procure artificially intelligent aircrafts where everything is automated and stress on pilot is decreasing day by day. One of the
important aspects of a modern aircraft is to show real time data during flight. This module covers all topics in this regard but specifically emphasizes on
the avionics systems related to sensors and displays.

M6. Materials & Hardware’s
The variety of materials and hardware used in aircraft engineering is vast, and this module deals with a broad group of materials, their main characteristics, properties, identification and uses.

M7. Maintenance Practices
Aspects of safe working practices on an aircraft, including precautions to take when working with electricity, gases especially oxygen, oils and chemicals
are taught here. Theoretical and practical aspects of maintenance practices are covered in this module and it’s required for both B1 and B2.

M8. Basic Aerodynamics
The theory of how an aircraft is able to fly in air is covered in this module from atmospheric aspects to stability of the aircraft. Since it’s a fundamental
module for every aircraft maintenance engineer so it required for both, B1 and B2.

M9. Human Factors
Aircraft maintenance engineer has a vital part in flight safety. To gain this understanding, AME must know a little of how the human body works, how the
brain processes information,  how we interact with others through effective communication and the types of human error that must be avoided while
performing maintenance tasks.

M10. Aviation Legislation
Airlines throughout the world have strong incentives to maintain high standards of safety. International laws in aviation are developed to enforce safety
standards and efficient working of the worldwide aviation. It’s necessary for every engineer to understand and implement international aviation laws.

M11 A. Aeroplane Aerodynamics Structure and Systems
The various systems and subsystems of an aircraft in detail are taught in this module. Airworthiness requirements for structural strength,
damage tolerance concepts and various other concepts of integrated systems are dealt with here.

M13. Aircraft Aerodynamics, Structures and Systems
The module covers avionics operational elements of an aircraft including but not limited to the flight control, auto-pilot, landing gears, etc.

M15. Gas Turbine Engine
Gas turbine engines are used to generate thrust force necessary to keep the aircraft in air. All aspects of a commercial aircraft engine are dealt with in
this module. All aspects of a commercial engine are handled here.

M16. Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine (although there are also pneumatic and hydraulic reciprocating engines) that uses one or more reciprocating pistons to convert pressure into a rotating motion.

M17. Propeller
Construction methods, Blade element theory and all the equipment related to the propeller assembly are covered in this module. Propellers are run
by a reciprocating engine and are used on a large number of aircrafts. All elements utilized for an efficient working of a propeller are included in this
