A Russian military helicopter has crashed at an air show before thousands of spectators, killing one crew member and injuring another.
Video footage clearly show the tail rotor failing and the gunship starting to spin uncontrollably before hitting the ground in an uncontrolled crash-landing:
"The commander has died, the second pilot is alive. According to the second pilot, equipment failure caused the accident," the head of the Russian Air Forces, Colonel General Viktor Bondarev, was quoted by the RIA Novosti news agency as saying.
The air show, Aviadarts, featured Russian Air Force plane and helicopter crews competing to fulfill timed assignments.
No spectators were injured, and the event was suspended for the day following the accident.
Russia's air force has used the Soviet-designed Mi-28 since the mid-2000s, and the aircraft is also exported to numerous countries, including Iraq.
Bondarev has grounded the country's Mi-28 fleet pending an investigation. The surviving crewmember who ejected, reports that hydraulic failure was to blame. This is the 4th crash of an Mi-28 due to hydraulic or gearbox failure.
There have been at least six incidents over the past few weeks involving Russian military planes and helicopters
