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. They also certify the Airworthiness or issue the flight release certificate concerning the 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.


As per the diagrammatic representation given above, which is based on data, given by CAPA, there is a huge demand for Aircraft Maintenance Engineering professionals throughout our world. As per estimation, in Asia Pacific itself, there is a demand for 2,56,000 engineers. If we look at the world figures, we need 6,48,000 Aircraft Maintenance Engineering personnel. These are the demand figures from 2017 to 2036, i.e. approximately 20 years.

Looking at the figures above for the Asia Pacific region, even if there is a 100 % pass rate, India will produce only 2200 candidates per year, means in 20 years approximately 44000, trained Aircraft Maintenance Engineering personnel. India and China among the largest countries in this region will be able to provide approximately 1 lac trained manpower. Other remaining small countries will contribute approximately 25000 trained manpower. Considering all these figures, the scope of Aircraft Maintenance Engineering personnel is too high in the market.

Indian government’s open sky policy, regional connectivity policy, and tax exemptions on the MRO industry are boosting Indian Aviation Industry to achieve laurels in the field. A lot of new Aircraft are being imported by Airlines, Scheduled operators, Non-Scheduled Operator, and Business house owners. All these factors are increasing the demand for skilled Aircraft Maintenance Engineering personnel.

Aircraft Maintenance Engineering personnel can apply for jobs in approximately 250 plus companies in India, to mention some of the companies and domains of aviation-related companies are as follows:

  • BSF, HAL, Taneja Aerospace, Mahendra Aerospace, Civil Aviation Department, DGCA, Scheduled Airlines, Non-Scheduled Airlines, Private Airlines, Government Airlines, MRO, AMO, TECHNICAL PUBLICATIONS etc.

About The Aircraft Maintenance Engineering Program

Training for the Aircraft Maintenance Engineering program at SOA has been approved by the DGCA. The license Examination is conducted by the DGCA. The duration of training at the institute is 2 years, phased over four semesters. This 2 Year has 2400 Hrs of planned training out of which 2050 Hrs will be in classrooms and labs, and 350 will be in the actual maintenance environment, i.e. at MRO. School of Aeronautics has tied up with Air India, which is India’s largest MRO. The Total Aviation Experience requirement to obtain a B 1.1 or B2 license is as per CAR 66. To obtain Aircraft Maintenance Engineering License in the B2 category students will have to clear 10 module examinations of DGCA, whereas for the B1.1 category students will have to clear 11 module examinations of DGCA. School of Aeronautics also provides conversion courses from B1.1 to B2 or B2 to B1.1


Different types of Airframe and Airframe Components, Engines and Engine Components, Aircraft Instrument System Components, Radio and Aircraft electrical equipment in our workshop allow the student to study various theories of Mechanical / Avionics of an aircraft. The reference books, periodicals, aviation magazines, and text books in our library keep the student abreast of knowledge in the aviation field. In short SOA provide all facilities to make a student a successful Aircraft Maintenance Engineer.


The course is meant to prepare the students for getting an Aircraft Maintenance Engineer License in various categories which is issued by DGCA after the student has passed the module examination conducted by DGCA.

Eligibility Criteria for Admission into the Aircraft Maintenance Engineering (AME) Program

The minimum qualification for admission to the course is a pass in

i. 10+2 pre-degree/intermediate or equivalent with Mathematics, Physics, and Chemistry / B.Sc with Maths, Physics & Chemistry.

ii. Diploma in Engineering.


Medical Standards For Admission Into Aircraft Maintenance Engineering

The student will have to produce a medical certificate from a registered medical practitioner with minimum MBBS qualification to certify that he / she has no physical disability and the color vision is normal.

Requirement To Hold A Licence Under Part-66 Aircraft Maintenance Engineering Licence

To be granted authorization to issue certificates of release to service a person must hold a valid Aircraft Maintenance Engineering licence issued by Part-66. The minimum age to hold a Part-66 license is 18 years. To certify, the minimum age is 21.

How To be an Aircraft Maintenance Engineer Under Part-66

Under Part-66 an Aircraft Maintenance Engineering license 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 Aircraft Maintenance Engineering License

The license is divided broadly between Mechanical and Avionic trade disciplines although given the various technologies and combinations applicable to certain aircraft, the Mechanical license category is further subdivided. In addition, various levels within the license 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 license categories.


The categories within the Aircraft Maintenance Engineering license 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 License

Category A is further divided into subcategories as follows:

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

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

Experience Requirements

An applicant for a category A license 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 of practical maintenance experience in operating aircraft.

Category B1 of Aircraft Maintenance Engineering License

The B1 license is mechanical-based 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 license. 

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