Substantially damaged at 16L00 CDT (Central Daylight Time) on July 5, 2008 when crashed at Canyon Lake, Cormal County, Texas (at approximate coordinates 29'91.6944"N, 98'30.5556"W). Two of the three person on board were uninjured, the third sustained minor injuries. According to the official NTSB report into the accident:
"The commercial pilot was conducting a photo flight with himself and two passengers in the four seat helicopter. The helicopter had been in a zero airspeed out of ground effect hover at approximately 40 to 50 feet above the ground for about 15 seconds when the pilot applied power to begin a vertical climb. According to the pilot, he then suddenly and without warning lost directional control, the helicopter began to spin nose right, and his application of full left pedal had no effect. The pilot initiated an autorotation and the helicopter landed hard on rough rocky sloping terrain between several trees. The crash caused substantial damage to the fuselage and airframe when the left skid gear partially collapsed and penetrated into the left rear passenger cabin floor area. The upper pylon was noticeably bent and wrinkled, and both main rotor blades were damaged. An on-scene investigation by an FAA maintenance inspector confirmed continuity and no apparent damage to the flight controls. There was no post-crash fire and the pilot and front seat passenger reported no injuries, but the left rear seat passenger suffered minor injuries and had to be carried out of the aircraft. The pilot reported the surface winds were light and variable, visibility 10 statute miles with scattered clouds at 3,000 feet, a temperature of 88 degrees, and an altimeter setting of 30.01 inches of mercury.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: A total loss of tail rotor effectiveness. Contributing to the accident was the pilot's improper decision to operate inside the height velocity curve."
Additional; Robinson R44 N804DF was repaired and returned to service, only to crash again on February 19, 2017 (see link #3)
