Flight tests of the Ka-226T helicopter with a Russian-made VK-650V engine have begun in Russia. The helicopter's maiden 20-minute flight included taxiing, hovering, and maneuvering. Stability, controllability, and component loads were tested. The tests confirmed the normal operation of the helicopter's powerplant and systems. The VK-650V is the first certified Russian engine for light helicopters up to 4 tons. The Ka-226T is modular; by replacing the rear module, it can be converted into a passenger, cargo, or medical evacuation helicopter. Module replacement takes no more than 45 minutes.

Russian Helicopters has delivered the first three production Mi-171A3 helicopters to Gazprom Avia. The helicopters have already flown from the Ulan-Ude Aviation Plant to Sakhalin Island, where they will be used to transport people and cargo to offshore fields. To ensure enhanced safety during offshore operations, the Mi-171A3 is equipped with an emergency ditching system and life rafts, allowing for emergency landings on water in an emergency. Furthermore, the helicopter is equipped with a crash-resistant fuel system, preventing fuel leakage and fire in the event of an emergency landing. The primary purpose of the Mi-171A3 is overwater flights at long distances from shore to support offshore platforms, transport personnel and cargo, and conduct rescue operations. The Mi-171A3 helicopter can be converted into a search and rescue version by installing a winch, medical modules, a searchlight, and other equipment.
