When global aviation sanctions severed Russia from the Western aerospace ecosystem in 2022, Aeroflot Group, one of the world’s largest Airbus narrowbody operators found itself confronting an existential maintenance challenge. Cut off from OEM-backed engine overhaul networks, spare parts channels and authorised repair centres, the flag carrier had to either rapidly rebuild domestic MRO capability or risk long-term fleet attrition.
Three years on, Aeroflot has reached a defining technical milestone: the successful completion of its first in-house overhauls of Western-built CFM56-5B engines, marking the beginning of Russia’s most ambitious civil aero-engine localisation effort to date.
First domestic CFM56 overhaul signal strategic breakthrough
Aeroflot confirmed that three CFM56-5B engines installed on its Airbus A320-200 fleet have been independently overhauled by AeroTrustTechnics, a wholly owned Aeroflot Group subsidiary created to anchor engine MRO, component repair and technical services localisation.
The milestone represents far more than a maintenance achievement, it is Russia’s first meaningful step toward civil aero-engine technical sovereignty under sanctions, proving that certified, safety-critical engine restoration can now be performed domestically without access to OEM shop networks.
CFM56-5B engines power a substantial portion of Aeroflot’s narrowbody fleet, making them the backbone of the carrier’s domestic and regional network. Their local overhaul capability directly safeguards route continuity, aircraft utilisation and long-term fleet viability.
Sanctions, spares and survival
Since 2022, Russian operators have lost access to OEM technical data updates, authorised engine repair centres, certified spare part pipelines and global component pooling networks.
As a result, airlines were forced into extreme asset preservation strategies including engine cannibalisation, reverse engineering, limited domestic repairs and internal pooling, to keep aircraft operational.
Aeroflot’s ability to complete certified CFM56 overhauls signals that it has crossed the hardest technical barrier in sanctions-era aviation: restoring life-limited, safety-critical rotating machinery without OEM supply chains.
Aeroflot has now confirmed plans to inaugurate a dedicated civil aero-engine repair megacentre by Q4 2027, which will significantly expand Russia’s domestic engine MRO capacity.
Initially supporting Aeroflot Group aircraft, the facility will be designed to offer third-party engine MRO services to other Russian airlines, creating a national civil engine sustainment hub.
Industry analysts note that achieving full engine MRO capability typically requires 5–7 years of tooling development, NDT infrastructure build-up, metallurgical capability, spare manufacturing substitution, and regulatory engineering validation, especially without OEM support.
Aeroflot has therefore effectively embarked on one of the world’s most technically complex aviation localisation programmes.
The new engine repair centre forms part of a broader strategy to reconstruct Russia’s civil aviation sustainment ecosystem covering engine and component repair along with parts
manufacturing substitution, domestic PMA-equivalent part development, tooling replication and reverse engineering and indigenous digital maintenance systems.
This signals a long-term pivot away from reliance on Western MRO ecosystems toward a sovereign maintenance architecture.
While structural MRO capability is rebuilt, Aeroflot is simultaneously using wet leasing as a tactical capacity stabilisation tool.
Aeroflot is currently operating three Airbus A330-300 aircraft wet leased from iFly Airlines, and is looking at additional wet-leased aircraft in 2026 following regulatory approvals granted in September 2024. This allows the carrier to protect long-haul network continuity while its engine MRO infrastructure matures.
Aeroflot’s engine overhaul milestone is not simply a maintenance story; it is one of the most technically audacious civil aviation rebuild programmes underway globally today.
By independently restoring CFM56 engines and committing to a 2027 megacentre, Aeroflot is reshaping what is technically possible under sanctions, rebuilding Russia’s civil MRO ecosystem from the inside out.
For the global MRO community, Aeroflot’s journey offers a stark reminder that engine MRO is not just about maintenance, it is about national aviation resilience, fleet sovereignty, and long-term air transport continuity.
And for that reason, Aeroflot is our Airline of the Month – January 2026.
