The Russian Il-114-300 turboprop aircraft has completed an additional stage of certification testing in the Arctic. The aircraft completed a series of takeoffs and landings from airfields on Novaya Zemlya and Franz Josef Land. The Il-114-300 is designed to develop regional air service and operate in a wide range of climate zones. The aircraft can take off and land from small airfields, regardless of the level of their ground infrastructure, including short runways. The aircraft is built entirely from Russian components and is powered by TV7-117ST-01 engines.

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.
