Russian media acquired information from top managers of several airlines operating the Sukhoi Superjet 100.
According to the information received, the cause of the small plaque is the problems that arise in the hot part of the SaM146 engine - cracks in the combustion chambers and oil sumps.
According to the interlocutors, cracks appear twice as fast as specified by the guarantee - after 2-4 thousand hours of flight instead of the stipulated 7,5-8 thousand hours.
This information was also confirmed by representatives of leasing companies buying these cars.
This part of the engine is produced by the French company Snecma, which is a division of the industrial conglomerate Safran SA.
According to experts, to correct the shortcomings of this part of the engine, huge investments and expansion of production are required.
However, the French company does not plan to change anything in the current production process.
Recall that at the start of the joint project it was planned to produce about 1300 Sukhoi Superjet 100 passenger aircraft per year, but at present their production does not exceed 595 units.
