EASA Part 66 B1.1 Modules

A Career In High Demand


Aircraft Engineers are highly sought after worldwide by airlines, maintenance organizations, Aviation Authorities and OEM's. Aerofix will make your profile even more attractive with a specialization in Aircraft Maintenance  that includes an EASA Part-66 B.1 Modules and considerable hands-on experience on modern aircraft. This four-year program equips you with both the theoretical knowledge and hands-on experience needed to thrive in the aviation industry. By the end of the course, you'll possess the skills required to plan, check and evaluate repairs but also to inspect, maintain, and repair by yourself a wide range of aircraft types and their components—making you an all round invaluable profesional for manufacturers, operators and other companies in the aviation sector.

4 Year Programme Overview

This program combines in-depth theoretical education with extensive practical training, offering a comprehensive learning experience over four years:

Years 1 & 2

In the first two years, you'll focus on foundational theory at TU-Sofia, complemented by practical training at Aerofix Aviation Academy's advanced workshops. You'll obtain a very solid theoretical foundation in mechanics, aerodynamics and propulsion in addition to developing key technical skills in mechanics and aircraft systems, learning essential techniques such as turning, milling, drilling, grinding, and part assembly.
