Aircraft Accident/Incident Report

Presidio, Texas 79845
Monday, February 24, 2014 13:30 CST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he was surveying ranch land and that the helicopter was hovering about 12 to 15 feet above the ground just before the accident. While transitioning to forward flight, the helicopter was unable to maintain sufficient power and altitude. The low rotor rpm horn sounded, and the pilot decreased the collective to try to “fly out of it,” but the helicopter was too close to the ground. The helicopter subsequently lost tail rotor effectiveness and spun around once before impacting the ground and rolling over. The pilot reported no mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot’s failure to maintain sufficient rotor rpm when transitioning the helicopter from a hover to forward flight, which resulted in a loss of helicopter control.
