The B1.1 stream is specifically for turbine-engine (jet-engine) aircraft the kind used in commercial airliners and many defence planes. As an AME B1.1 engineer, you learn to inspect, maintain, repair, and troubleshoot a broad range of mechanical and engine systems, ensuring each aircraft is safe and airworthy before flight.
You study a wide range of subjects under a DGCA-approved syllabus maths physics aerodynamics electrical and electronics fundamentals, materials and hardware, maintenance practices, aircraft structures and systems gas turbine engines, and aviation legislation. This theoretical grounding helps you understand how aircraft systems work, why they must be maintained carefully, and what regulations and safety rules govern aviation maintenance.
A key part of the course is hands-on work: you get to work with real turbine engines and aircraft mechanical systems. You learn to disassemble and reassemble engines do performance checks and ground runs, inspect turbine blades and compressors, check fuel hydraulic pneumatic and other systems and practice troubleshooting. This practical exposure often in workshops or hangars prepares you for real-world tasks of maintenance repair, and certification of aircraft.
The B1.1 program spans about 2400 hours usually over 2 to 3 years depending on the institute. On successfully completing the course (with both theory and practical training) and meeting regulatory requirements you become eligible for a B1.1 licence from the Directorate General of Civil Aviation (DGCA). This license allows you to legally inspect maintain repair, and certify turbine-engine aircraft.
You get a strong theoretical foundation understanding aircraft mechanics aerodynamics materials electronics, safety regulations and more.
You gain real world hands on skills working with actual engines and systems, preparing you for the demands of aviation maintenance.
You qualify for a DGCA-approved licence, which is highly respected in India and often accepted internationally opening up career opportunities at airlines, maintenance organizations (MROs), aircraft manufacturers and defence aviation.
The B1.1 stream is ideal if you love mechanical systems, enjoy practical work, and wish to play a vital role in aviation safety and aircraft operations.
