Sibir Technic, a subsidiary of the ENGINEERING Holding is the first MRO company in Russia to start providing light base maintenance, the A- check on Embraer E170 regional jets.

Russia's only operator of Embraer E170, S7 Airlines launched operation of this type in the spring 2017.

Sibir Technic's maintenance staff received appropriate training and rat- ings in Europe, and have already completed A-checks on several Brazilian-built aircaft at the company's certified facility at Novosibirsk's Tolma- chevo airport. Sibir Technic provides maintenance on Embraer E170 completely in-house without involving any third party assistance.

"By the time our technicians started their first A-check on E170, they'd already had accumulated extensive knowledge of the aircraft and its maintenance of the type. They built experience both during their training and internships in Europe, and also while providing line maintenance on E170s for S7 Airlines in Russia," Sergey Falshin, head of frequent checks unit at Sibir Technic. "A-check implies a deeper inspection and mainte- nance of an aircraft that line maintenance."

The interval between A-checks on Embraer E170 is 750 flight hours, and the checks typically takes 12 hours. Since S7 Airlines operates its aircraft very intensely, the period between A-checks never exceeds three months. To ensure that the checks does not cause disruptions to flight schedule, the works are usually done during night time.

ENGINEERING Holding has plans to provide the entire range of maintenance checks on Embraer E170.
