Aircraft Maintenance Engineering (AME) B1.4 Stream is very popular among aircraft maintenance courses. This stream focuses on helicopter turbine engines, mainly used in defense, rescue operations, offshore services, and VIP transport.
An AME B1.4 engineer is responsible for inspection, maintenance, repair, and troubleshooting of mechanical and engine systems of helicopters operated by jet engines. The primary objective of an AME engineer is to ensure safety and airworthiness standards set by DGCA.
This course is approved by the Directorate General of Civil Aviation (DGCA), Government of India. The AME B1.4 stream is a licensed program that opens various career opportunities at national and international levels.
The B1.4 stream of Aircraft Maintenance Engineering primarily deals with turbine engine-powered helicopters. These are rotary-wing aircraft operating with advanced turbine propulsion systems, used in medical emergencies, search and rescue, aerial surveillance, and transport.
Students pursuing this stream learn about:
This stream demands strong technical understanding, problem-solving skills, and in-depth knowledge of aviation mechanics and helicopter aerodynamics.
The AME B1.4 course duration is around 2 to 3 years, designed to train students to become licensed Aircraft Maintenance Engineers for turbine engine helicopters. It covers both theoretical and practical training, including aircraft systems, maintenance practices, and aviation regulations. The program contains 2400 hours of training as per DGCA rules and requirements, including practical sessions on real helicopters to understand real-life challenges and develop skills to clear DGCA licensing exams.
The DGCA-approved syllabus ensures students gain detailed theoretical knowledge and practical skills in turbine helicopter maintenance.
