Introduction:
If you’re an aspiring or current Aircraft Maintenance Engineer (AME) in India, understanding the shift in licensing regulations under AAC 04 of 2017 is critical.
The DGCA introduced this framework to modernize India’s AME licensing system, align it with international standards (specifically EASA Part-66), and bring transparency to qualification and endorsement procedures.
This blog will explain the key highlights of AME licensing under AAC 04/2017, and how it affects your career progression.
What is AAC 04 of 2017?
AAC 04/2017 was issued by the Directorate General of Civil Aviation (DGCA) to standardize and digitalize the AME licensing process.
It introduced the concept of a Modular Examination System and License Categorization in line with the global best practices under CAR-66 and EASA Part-66 frameworks.
✅ Key purpose:
- Modernize the AME licensing process
- Improve clarity on licensing categories and privileges
- Simplify the issuance, extension, and renewal of licenses
- Ensure safety compliance in aircraft maintenance
Main Features of AME Licensing under AAC 04/2017:
🔹 Modular Examinations:
- Examinations are divided into modules (subject-wise).
- Candidates can pass modules separately and accumulate them over time.
- No need to clear the entire examination at once.
🔹 License Categories: The AME License is now issued in the following categories:
- Category A: Line maintenance certification (mechanical or avionics limited scope)
- Category B1: Mechanical stream (airframe, engine, electrical systems)
- Category B2: Avionics stream (electrical, instrument, radio, navigation systems)
- Category B3: Non-pressurized aircraft below 2000 kg MTOW (mainly piston engine)
- Category C: Base maintenance certifying staff (requires broader approvals)
🔹 Practical Experience Requirement:
- Candidates must complete approved practical training and show work experience.
- This experience is mapped module-wise and category-wise.
🔹 Digital Licensing via eGCA:
- Applications for license issuance, renewal, and endorsement must now be submitted through the eGCA portal.
- Entire history (modules passed, experience gained) is now recorded online.
Benefits of AAC 04/2017 for AMEs:
🔹 Modular exams give flexibility — clear subjects at your pace.
🔹 License holders get internationally comparable qualifications.
🔹 Easier license endorsement and renewal online via eGCA.
🔹 Greater transparency and faster processing from DGCA.
🔹 Alignment with international aviation maintenance standards (EASA Part-66).
