Aircraft Maintenance Engineering is a professional program, after doing which students become eligible to certify the airworthiness of Aircraft before each flight or after any minor or major repair and maintenance. AME’s also certify the Airworthiness or they issue the flight release certificate in respect to Aircraft Component after minor or major repairs. Aircraft Maintenance Engineering candidates are the highest paid engineers in the world, in comparison to any other branch of engineering. Financial development of Aircraft Maintenance Engineering is too fast.


Most people become an Aircraft Maintenance Engineer (AME) by attending a approved school registered under the National Airworthiness Authority of the country. In what is typically an 2 years program, they must learn everything that is required for maintenance of a typical airplane. AMEs must also learn all of the sections of the Local Aviation Regulations which pertain to them. Once the AME has completed this and pass the necessary exams, the AME will be given a Licence Without Type Rating (LWTR) for the relevant trade. In order to be type certified / type rated, AMEs must either go for another exam with the Local Aviation Authority for a specific type aircraft, normally small aircraft (based on aircraft weight); or attend a course and exam with the Quality Assurance Department of an Approved Organization / Airlines, normally for larger aircraft.


The different categories are:

  • Mechanical Branch (B1.1).
  • Avionics Branch (B2).


Note: Mechanical Branch is further divided into fixed wing and rotary wing.


Also, in time, AMEs can advance and diverse to other sides of Aircraft Maintenance Engineering (AME), such as to quality assurance department as inspectors, to maintenance planning.


Aircraft Maintenance Engineering (AME) is not a degree or a diploma course, but a License program. On completion of the training, a license is issued by the Directorate General of Civil Aviation (DGCA). Recently AICTE has introduced nomenclature of B.Tech (AME).


During the training, lessons are imparted for service and maintenance of aircraft so as to ensure flight safety. A two year Aircraft Maintenance Engineering license training course is being offered by several Institutes approved by the DGCA


Aircraft Maintenance Engineering (AME Admission) Course is a 2 years course divided into 4 Semester. The license Examination is conducted by the DGCA. The duration of training at the institute is 2 years, phased over four semesters. This 2 Years is having 2400 Hrs of planned training out of which 2050 Hrs will be in class rooms and labs, 350 will in actual maintenance environment. This two years training programme enables students to appear in various modules of the DGCA exam and acquire license. Students are required to pass the semester exams of institute to be appear for DGCA License exam. At the end of course, course complition certificate is also issued to students from the college as per DGCA requirements.

How To be an Aircraft Maintenance Engineer (AME) Under Part-66

Under Part-66 an Aircraft Maintenance Engineering licence confirms that the person to whom it refers has met the Part-66 knowledge and experience requirements for any aircraft basic category and aircraft type rating specified in the document.

Types of AME (Aircraft Maintenance Engineering) License

The licence is divided broadly between Mechanical and Avionic trade disciplines although in view of the various technologies and combinations applicable to certain aircraft the Mechanical licence category is further subdivided. In addition there are various levels within the licence that allow the holder to be authorised to perform certain roles within line and/or base maintenance. These reflect different levels of task complexity and are supported by different standards of experience and knowledge. An individual may hold a combination of licence categories.


The categories within the Aircraft Maintenance Engineering licence are:

  • Category A : Maintenance Certifying Mechanic
  • Category B1 : Maintenance Certifying Technician (Mechanical)
  • Category B2 : Maintenance Certifying Technician (Avionics)
  • Category C : Base Maintenance Certifying Engineer


Category A of Aircraft Maintenance Engineering (AME) License

Category A is further divided into sub categories as follows:

  • A1 : Aeroplanes Turbine
  • A2 : Aeroplanes Pisto
  • A3 : Helicopters Turbin
  • A4 : Helicopters Piston

The experience demonstrated on application must be relevant to the sub category of licence being applied for and must satisfy certain criteria in respect of recency.

Experience Requirements For Cat A

An applicant for a category A licence must have completed a prescribed period of Aircraft Maintenance Engineering experience. This experience should include minor scheduled line maintenance and simple defect rectification on operating aircraft. Category A applicants should have at least 2 years practical maintenance experience on operating aircraft.

Category B1 of Aircraft Maintenance Engineering (AME) License

The B1 licence is a mechanical based licence and permits the holder to issue certificates of release to service following line maintenance, including aircraft structure, power plants and mechanical and electrical systems. Replacement of avionic line replaceable units requiring simple tests without the use of test equipment to prove their serviceability is also included within the privileges of this licence. 

The B1 licence is sub-divided into sub-categories as below:

  • B1.1 : Aeroplanes Turbine-Engine
  • B1.2 : Aeroplanes Piston-Engines
  • B1.3 : Helicopters Turbine-Engine
  • B1.4 : Helicopters Piston-Engines

Experience Requirement  Aircraft Maintenance Engineering B1 Category

An applicant for a category B1 licence must have completed a prescribed period of aircraft maintenance experience. This experience is to be relevant to the licence category required and to the maintenance experience of operating aircraft. This experience should include maintenance on aircraft structure, powerplant, mechanical and electrical systems and replacement of avionic LRU’s requiring simple tests to prove their serviceability. Candidates should have at least 4 years practical maintenance experience on operating aircraft.


Category B2 of Aircraft Maintenance Engineering License

The B2 licence is avionic based and permits the holder to issue certificates of release to service, following line maintenance on avionic systems. A Category B2 licence holder also has a role in base maintenance.


The B2 Aircraft Maintenance Engineering licence broadly covers the following areas:

  • Instrument Systems
  • Automatic Pilot Systems (fixed and rotary wing), including Auto-throttle and Auto-land Systems
  • Radio Communication, Navigation and Radar Systems
  • Electrical Power Generation and Distribution to Avionic Systems

Experience Requirements For Obtaing Aircraft Maintenance Engineering Licence in B2 Category

An applicant for a category B2 Aircraft Maintenance Engineering licence must have completed a prescribed period of aircraft maintenance experience. This experience is to be relevant to the licence category sought and to the maintenance experience of operating aircraft in avionic and electrical systems. Category B2 applicants should have at least 4 years practical maintenance experience on operating aircraft.


Aircraft Maintenance Engineering is a 2 years program divided into 4 semesters. All the semester has theoretical and practical classes as per DGCA norms. Every semester will have 40 % theory classes and 60 % practical classes.

Knowlegde Upgradation For AME Students

Knowledge Upgradation


An Aircraft Maintenance Engineering (AME) can continuously upgrade his knowledge with new upcoming sophistication doing Approved courses (type training) on Aircrafts, which will be sponsored by the organization in which student is working. There are AME’s in India who are working as freelancer Engineers

Accrediation of AME Program

Course Accrediations of AME

Accredited courses address industry, enterprise, educational, legislative or community needs that are not covered in nationally endorsed Training Packages. Accredited courses can respond to changing skill requirements, including changes to the needs of emerging and converging industries and sectors.


Why have a course is accredited ?

Course accreditation is formal confirmation that the course:

  • is nationally recognized
  • meets an established industry, enterprise, educational, legislative or community need
  • provides appropriate competency outcomes and a satisfactory basis for assessment
  • meets national quality assurance requirement
  • participant/employer financial assistance through various government agencies
