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 instructional helicopter flight impacted terrain during a hover taxi while being piloted by a non-rated helicopter pilot seeking to accumulate flight time towards a helicopter rating. Dark night conditions prevailed at the time of the accident. A rated helicopter pilot who did not hold certified flight instructor certificate was seated in the left pilot seat. The non-rated pilot began a right turn to taxi to a taxiway when the turn rate began to accelerate rapidly. The rated pilot attempted to regain control of the helicopter by applying a left pedal control input before the helicopter impacted the ground.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The directional control not maintained by the unrated helicopter pilot, and the remedial action not performed by the pilot-in-command. The pilot-in-command's lack of certification as a certified flight instructor and the dark night conditions were contributing factors.
