Ukrainian engine manufacturer Motor Sich has brought to MAKS a substantial upgrade solution for the Mil Mi-2 light helicopter. CEO Vyacheslav Boguslayev says Motor Sich is not seeking recognition as the new variant’s developer, but notes that this is the term the CIS-wide Interstate Aviation Committee (IEC) applies to any company applying for a separate type certificate. In order to be able to apply with the IEC for certification of the upgraded helicopter, Motor Sich had to rename it MSB-2. "Our design house has never been through a certification process before, and we appreciate the opportunity we have to gain valuable knowledge of this complex procedure with an already well-reputed airframe," says Boguslayev.
Composites account for 25% of the MSB-2 fuselage. The helicopter has new engines and a new reduction gear. The main fuel tank is mounted externally. Forward-facing cabin seats are arranged in two rows; access to the cabin is through a ramp door in the rear part of the fuselage.
