The Diploma in Aircraft Maintenance Engineering offered by colleges in Delhi NCR, such as Puran Murti Campus, typically lasts three full academic years. This duration is structured into six semesters, with each semester spanning approximately six months. During these semesters, students engage in a blend of theoretical classroom instruction and hands-on practical training.
The first year of the course primarily focuses on building a strong foundation in core engineering and science subjects. These include basic electrical and mechanical systems, physics, mathematics, engineering drawing, and materials science—all essential for understanding how aircraft systems operate.
In the second year, the curriculum becomes more specialized and technical, introducing students to aircraft-specific subjects such as airframe systems, engine operations, avionics, and maintenance practices. Here, students also begin working directly in aviation workshops and laboratories, where they gain practical exposure by handling real aircraft components and tools under the guidance of trained instructors.
The third and final year is often more intensive and industry-oriented, where students delve into advanced topics such as aircraft inspection techniques, troubleshooting, regulatory compliance (DGCA and EASA standards), safety procedures, and human factors in aviation. During this phase, many colleges include internships, live training on aircraft, or industrial visits, ensuring students are industry-ready by the time they graduate.
Some diploma programs may also align with EASA or DGCA licensing modules, allowing students to start preparing for aviation maintenance certification exams alongside their academic training. This makes the three-year diploma highly valuable, as students not only complete their academic qualification but also begin their journey toward becoming licensed aircraft maintenance engineers (AMEs).
