A Russian Mi-28 attack helicopter crashed during a aerobatic display, in Ryazan, Russia.
The chief pilot was killed and the co-pilot sustained the crash.The helicopter went into a flat altitude spin, following which it crashed. The co-pilot reported, the emergency alert system indicated a hydraulic boost failure.
The video validates the claim as the main rotor and tail rotors is seen rotating at the required speed.
Hydraulics are used to reduce the force required by pilots to control the helicopter. Failure to these systems make the helicopter hard to control, especially the powerful military helicopters, hence redundant hydraulic systems are provided.
Russia's Air Force Commander-in-Chief Viktor Bondarev has ordered the grounding of all Mi-28 helicopters following the crash.
