The Mi-38 programme has been delayed as Pratt & Whitney Canada, initially chosen as the preferred supplier, planned to pull out of the project due to a US embargo on sales of dual-purpose equipment to Russia.
The second Mi-38 helicopter prototype is fitted with Canadian PW 127/TS engines, but can also be equipped with Russian TV7-117V engines.
The helicopter is also fitted with modified main rotor blades and a Tranzas glass cockpit avionics system, and is currently being tested for a further full flight-test cycle.
A third prototype is currently being assembled at the Kazan Helicopter Plant in Tatarstan, according to RIA Novosti.
The twin-engine Mi-38 can either accommodate 30 passengers or carry a payload of 5 ton.
