This period includes both classroom/theory instruction and hands-on practical training. Schools offering B1.3 training follow the standards set by the Directorate General of Civil Aviation (DGCA), Government of India. Many institutes bundle roughly 2400 hours of total training mixing theory and practical sessions to meet regulatory requirements.
Theoretical classes: You will learn about helicopter turbine engine systems aerodynamics for rotary aircraft hydraulic and electrical systems safety procedures and aviation regulations.
Practical training: You will work on real helicopter turbine engines and systems, perform maintenance tasks, inspections, troubleshooting under supervision.
Exams and certification process: After training you must pass DGCA-approved module exams and log required maintenance experience to qualify for the B1.3 license.
Some institutes may complete the academic + practical portion in about 2 years (roughly 4 semesters), then expect additional real work maintenance exposure before license issuance.
The AME B1.3 course length is not a fixed one size fits all. In most DGCA approved institutes you can expect 2-3 years of formal study and training, totaling 2400 hours, covering both theory and hands on work on helicopter turbine systems. After this you complete exams and required maintenance experience to get licensed.
