NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The student pilot was attempting to land the helicopter on a trailer in order to transport it to another location. A witness reported that, while the helicopter was hovering above the trailer, it started to drift backwards. Subsequently, the nose of the helicopter rose, the tail struck the ground, the helicopter rolled to the right, the main rotor blades struck the ground, and the helicopter came to rest on the right side of the fuselage, which resulted in substantial damage. A postaccident examination of the helicopter did not reveal any mechanical malfunctions or abnormalities that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot’s failure to maintain control of the helicopter while landing, which resulted in a tail rotor ground strike and collision with terrain.
