Robinson R-22 Beta
The helicopter contacted high vegetation and rolled over while maneuvering at low altitude. The pilot reported that he went over a small hill into a ravine. As he tried to gain altitude to climb out of the ravine, rotor rpm decayed. The pilot turned the helicopter; however, the right skid hooked onto vegetation. The helicopter rolled over separating the main rotor system, tail boom, and tail rotor.
On March 22, 2005, about 1000 mountain standard time, a Robinson R-22 Beta, N716GH, contacted high vegetation and rolled over while maneuvering at low altitude near Waddell, Arizona. Gold Coast Aviation was operating the helicopter under the provisions of 14 CFR Part 91. The commercial pilot and one passenger were not injured; the helicopter sustained substantial damage. The personal local flight departed Glendale, Arizona, about 0900. Visual meteorological conditions prevailed, and no flight plan had been filed. The pilot and passenger rented the helicopter from Gold Coast Aviation with an intended flight from Glendale to Tucson, Arizona. Prior to departure, the pilot and passenger agreed that they would fly north for a photo flight over the passenger's house before heading to Tucson. The pilot reported that after the photo flight, they proceeded westbound to try to locate a few of his friends who were riding in the desert. He stated that he never intended on landing, but after locating them, he decided to land. The pilot reported that he went over a small hill into a ravine. As he tried to gain altitude to climb out of the ravine, main rotor rpm decayed. The pilot turned the helicopter; however, the right skid hooked onto vegetation. The helicopter rolled over separating the main rotor system, tail boom, and tail rotor. The pilot stated that the helicopter and engine had no mechanical failures or malfunctions during the flight. The operator submitted a Pilot/Operator Aircraft Accident Report (NTSB form 6120 1/2). The pilot did not submit an NTSB Form 6120. 1/2, but did submit a written statement.
the pilot's failure to maintain adequate rotor rpm and obstacle clearance, resulting in a dynamic rollover and collision with terrain.
