Aircraft Maintenance and Repair

Aeroflot Group has an efficient aircraft maintenance, repair, and overhaul (MRO) system aimed at ensuring high fleet reliability, flight safety and on-time performance.

The MRO policy of Aeroflot Group airlines provides for strict compliance with the requirements of countries of registration, maintenance programmes and aircraft lease agreements. It is focused on enhancing capacity and technical competencies, rolling out cutting-edge technological solutions and providing employee training and development opportunities while improving economic efficiency.

Each of the Group companies has departments responsible for airworthiness and maintenance of operated aircraft. Aeroflot Group has in place a strategic programme to centralise maintenance of aircraft and components for Aeroflot and subsidiary airlines. The centralisation provides for separating base and line maintenance.

PJSC Aeroflot’s Aircraft Maintenance Department holds and maintains certificates issued by European, Bermudian, and Russian aviation authorities for maintenance of the following types of aircraft and components:

  • Airbus А320F (Line maintenance, A-check, C-check, 6YE-check);
  • Boeing 737 (Line maintenance, Base maintenance);
  • Airbus A330 (Line maintenance, A-check, C-check);
  • Boeing 777 (Line maintenance);
  • SSJ 100 (Line maintenance, Base maintenance);
  • Airbus A350 (Line maintenance).

Scheduled maintenance of all types of operated aircraft is performed under programmes developed in line with the guidelines provided by aircraft and key components manufacturers. Maintenance of key aircraft components, such as engines, landing gear, and auxiliary power unit (APU) is performed by third-party contractors.

The Company serviced 145.3 thousand takeoffs at Sheremetyevo (base airport) in 2019, up 9.3% year-on-year. Labour intensity per flight hour of Aeroflot fleet aircraft was 2.00 hours in 2019 (vs 2.27 in 2018).

In addition to own fleet maintenance, the Company offers maintenance services to third-party customers. Technical support services were provided to 31 airlines (including foreign ones) and 42 aircraft operators and MRO companies in 2019. During 2019, around 40% of Aeroflot airline’s fleet heavy maintenance operations were performed by in-house maintenance facilities and 61% were carried out by contractors.
