With the current dynamics in place a steady improvement of indicators is expected.


Any aircraft OEM is constantly working on improvement of AC reliability through all its life-cycle. SCAC is permanently implementing the program of SSJ100 reliability improvement covering a full set of support services rendered to operators and consisting of a comprehensive plan of design, production, information and administration actions a major part of which has been already implemented. At the same time it’s necessary to underline that each operator plans for itself when to put the aircraft on ground for scheduled maintenance, defects rectification and embodiment of Service Bulletins.


For its own part, in order to increase AC operation efficiency SCAC has ensured 95% replenishment of the warehouses. Operator’scritical requests performance has increased by more than two times. Improvement of these parameters was possible due to growth of replenishment of the feeding warehouse in Zhukovsky by several times.
