Why work with us?

EASA PART-147 certified

Avia Prime MRO’s are EASA certified facilities, helping you to become a B1.1/B2 engineer. We provide in house training for certain aircraft types for our workers, as well as OJT and regular, law-required trainings. In addition to the EASA strict rules, we enhanced our training capabilities by adding virtual-reality general familiarization-like training videos, so our workers can be up to date and know the aircraft before their first real-life encounter. Virtual and Augmented Reality is also used by our companies to help you get to know rare procedures and enhance safety. We introduced the Run-Up simulator for B737NG to make sure our trainees know the safety procedures and work out kinetic memory, rather than wait for actual run-up on aircraft. That way you can get to know the procedure, conducting it a few times in a simulator.

We constantly learn and improve our practices, based on our Customers’ nearly 100-year experience. We try to change the face of modern aircraft maintenance ourselves, by testing new technologies and working on better, more efficient and accurate ways to test or repair the equipment.
