S7 Technics says its volume of maintenance work increased 2.5 per cent year-on-year in 2020. The company performed 413 A checks and 84 C checks.

S7’s technical specialists spent 2.035 million standard hours on maintenance work, which was 5.5 per cent less than in 2019. The decrease was down to a drop in the number of linear forms performed due to limitations associated with the Covid-19 pandemic.


The Russia-based company repaired and handed to customers more than 21 aircraft engines, some of which were repaired by its engine repair shop at Mineralnye Vody.

S7 said it was forced to adapt its activities to changing market demand in the wake of the Covid-19 situation, with the structure of the work it performed “redistributed”. The company restructured its operations to focus on base maintenance, engineering services and redelivery checks.

The measures “helped to evenly distribute the loading of hangars, since a large amount of base maintenance was performed during the summer period, when the intensity of fleet operation by airlines was reduced”, S7 said.

Measures also included an internal reallocation of engineering and technical specialists to the most relevant areas of work. “The measures taken made it possible not only to avoid cuts in production staff, but also to recruit qualified specialists, while other companies reduced the number of staff to minimise costs,” the company said.

S7 Technics deputy general director for economics and finance Roman Fedorov commented: “In 2020, S7 Technics continued to invest in most of our projects. These are works on the reconstruction of the building at Sheremetyevo Moscow Airport, where workshops for the repair of auxiliary power units (APU) and hospital repair of aircraft engines will be located, as well as a project for the construction of additional hangar areas in Novosibirsk.

“In the next two years, we plan to get a permit to perform maintenance of the APU and major repairs of the CFM56-5B/7B engines.”

In 2021, S7 Technics said it would focus on providing engineering support services, redelivery checks and engine repairs. The MRO provider also plans to expand its client portfolio by working with foreign companies, air cargo carriers and lessors.
