Incident Overview
The helicopter experienced a dynamic rollover and impacted terrain during an attempted takeoff from a parked trailer. According to a pilot acquaintance of the pilot, the trailer was a modified boat trailer with an open, trough-shaped platform surrounded by "D" shaped tie down rings. The acquaintance did not think the trailer was suitable for safe takeoff and landing operations.
Sequence of Events
Earlier in the day, the pilot made several unsuccessful attempts to land the helicopter on the recently purchased trailer. The pilot then opted to land on the runway surface next to the trailer. After obtaining fuel, the pilot decided to make an additional attempt to land on the trailer in dark night conditions. Witnesses observed the helicopter land on the trailer.
The Accident
Shortly after touchdown, the pilot attempted to depart the trailer platform. As the helicopter lifted off, the left skid caught on one of the numerous "D" shaped rings affixed to the platform surface of the trailer. The helicopter then experienced a dynamic rollover and collided with the ground.
