Aircraft Maintenance Engineering Syllabus | Latest Update
Aircraft Maintenance Engineering Syllabus | Modules | Subjects
Aircraft Maintenance Engineering (AME) is a unique and specialised curriculum unlike any other engineering program designed and approved by DGCA, Govt. of India. Hence, understanding the Aircraft Maintenance Engineering Syllabus or Modules, or Subjects is extremely important before taking admission to the AME course. Furthermore, not only the AME syllabus but also knowing the complete Aircraft Maintenance Engineering Course Details is very important. We all know that, in most conventional engineering programs, the syllabus primarily revolves around Physics, Chemistry, and Mathematics (M1, M2, etc.), with the first year being common for all major branches. However, Aircraft Maintenance Engineering stands apart. It is the only kind of engineering curriculum where Physics, Chemistry, and Mathematics are not direct core subjects, yet their fundamental concepts, which are inseparable from science and technology, are deeply integrated from a very basic level again. Whether students studied with a fully focused and concentrated manner in their early education of 12th Science PCM or a diploma in engineering, irrespective of their efforts, the AME syllabus ensures that all necessary basics are revisited and reinforced from the ground up. This is the beauty of this course. It builds strong technical foundations for every learner, regardless of prior exposure, and transforms them into skilled aviation professionals ready to handle real aircraft systems.

⚙️ Why the AME Syllabus |Modules | Subjects Matters
All students, parents, and aviation aspirants should boldly note that the profession of Aircraft Maintenance Engineering carries immense dignity and responsibility. The primary duty of an Aircraft Maintenance Engineer is to ensure that every aircraft remains fit to fly — in aviation terms, airworthy.
Aircraft are highly sophisticated and advanced technological machines that operate thousands of feet in the air. The responsibility to maintain their airworthiness is delegated by the regulatory authority of each country in accordance with national aviation rules and international standards. These standards are established under the Standards and Recommended Practices (SARPs) of the International Civil Aviation Organisation (ICAO).
Hence, clearing all required DGCA-prescribed AME modules to understand such advanced technologies is absolutely vital. AME aspirants must take their syllabus and training very seriously, as mastering these modules is one of the key requirements for obtaining the Aircraft Maintenance Engineer’s License.
📘 What Are The AME Modules?
Depending on the Aircraft Maintenance Engineering Licensing Categories and their sub-categories, the syllabus of an Aircraft Maintenance Engineering course is divided into various AME modules. In simple words, AME modules are nothing but Aircraft Maintenance Engineering subjects. These Aircraft Maintenance Engineering Modules are used to be divided across all semesters/ course duration of the complete Aircraft Maintenance Engineering curriculum.
List of AME Modules:
Module 1 Mathematics
Module 2 Physics
(Important Note: Module 1 (Mathematics) and Module 2 (Physics) are not applicable and hence not required to be passed separately.
This exemption exists because one of the eligibility criteria for admission into the Aircraft Maintenance Engineering (AME) course is completion of 10+2 with Physics, Chemistry, and Mathematics (PCM) or an equivalent Diploma in Engineering.
Since students have already studied and cleared these fundamental subjects during their earlier education, it is understood that they already possess the required foundational knowledge in Mathematics and Physics. Therefore, these modules are considered fulfilled by qualification and are not part of the DGCA AME licensing examinations.)

AME students are required to pass only the relevant modules that are applicable as per their chosen category and interest in the course category. It means all the above-mentioned modules do not apply to all categories of the AME licence. Each Licence category has its own set of module requirements that align with the specific aircraft group, systems and components, and type of maintenance (Tasked Trained Line Maintenance or Complete Line Maintenance) to be performed thereon. Let's understand applicable AME modules as per different licence categories as defined under CAR-66 by the Directorate General of Civil Aviation (DGCA), India.
1. For AME Licence Category A:
As per the type of Maintenance and type of Aircraft, (Maintenance type: Task Trained Line Maintenance and Aircraft Type: an Aeroplane fitted with a Turbine Engine/ Piston Engine & a Helicopter Fitted with a Turbine/ Piston Engine) the AME Licence category A is divided into its subcategories A1 (Aeroplane Turbine), A2 (Aeroplane Piston), A3 (Helicopter Turbine) and A4 (Helicopter Piston). So let's understand the applicable module as per the sub-categories of Category A Licence.
1.1 List of AME Modules applicable for Category A1 Licence:
Module 3 Electrical Fundamentals
Module 4 Electronic Fundamentals
Module 5 Digital Techniques/Electronic Instrument Systems
Module 6 Materials and Hardware
Module 7A Maintenance Practices

Module 10 Aviation Legislation
Module 12 Helicopter Aerodynamics, Structures and Systems
Module 16 Piston Engine
2. For AME Licence Category B1:
As per the type of Maintenance and type of Aircraft, (Maintenance type: Complete Line Maintenance and Aircraft Type: an Aeroplane fitted with a Turbine Engine/ Piston Engine & a Helicopter Fitted with a Turbine/ Piston Engine) the AME Licence category B1 is divided into its subcategories B1.1 (Aeroplane Turbine), B1.2 (Aeroplane Piston), B1.3 (Helicopter Turbine) and B1.4 (Helicopter Piston). So let's understand the applicable module as per the sub-categories of Category B1.1 Licence.
Important Note: If a student successfully clears all the modules under a particular sub-category of the B1 licence, it automatically includes the privileges of the corresponding sub-category of the Category A licence — but not vice versa.
In simple terms, clearing B1 modules offers broader privileges and a deeper technical understanding compared to Category A. Therefore, pursuing and passing the B1 category modules is always more beneficial than limiting oneself to Category A.
It’s important to understand that there is no change in the list of modules between Category A and Category B1 of the Aircraft Maintenance Engineering licence. The main difference lies in the depth of knowledge and complexity of the questions asked in the DGCA examinations, which are categorised into Level 1, Level 2, and Level 3.
In Category B1, the examination questions are generally more technical and in-depth, demanding a stronger understanding of aircraft systems, maintenance procedures, and troubleshooting.
This variation exists because Category B1 licence holders are trained and authorised for complete line maintenance of aircraft, whereas Category A licence holders are limited to specific task-based line maintenance. In simple terms, Category B1 engineers have broader privileges and greater responsibilities compared to Category A engineers, making the B1 modules tougher but more rewarding in the long run.
