Introduction
A helicopter pilot was conducting a positioning flight under night visual meteorological conditions while wearing night vision goggles (NVGs). The pilot followed a road that separated the departure point from the destination, reporting clear visibility of vehicle traffic and the surrounding terrain.
Flight Details
Approximately 15 minutes into the flight, the pilot sensed that something was wrong. The attitude indicator displayed the helicopter in a 60- to 70-degree left descending turn. The altimeters and airspeed indicators showed consistent trends, confirming the unusual attitude. The pilot attempted to correct the flight attitude but became disoriented.
Accident Sequence
Unable to recover from the disorientation, the helicopter impacted terrain. Upon impact, the helicopter rolled onto its right side. A post-impact fire ensued, which destroyed the helicopter.
Outcome
The helicopter was destroyed by the fire. The investigation did not specify injuries to the pilot or any other individuals. The probable cause of the accident was not stated in the source material.
