NTSB Narrative Summary Released at Completion of Accident
The helicopter approached the trailer, and landed "softly," with the nose canted slightly to the helicopter's right. The helicopter then lifted until it was "light on the skids," and drifted left until the left skid was suspended above the ground, off the left side of the trailer. The helicopter then settled onto the trailer and the left skid "fell' toward the ground. The pilot stated that at that point, one skid felt like it was "a pivot point, it felt like 'dynamic rollover'. I pulled too much collective, it got out of control, and I couldn't recover." The helicopter spun around the aft side of the trailer, and collided with the ground on the right side of the trailer. The pilot said that the flight to the port was uneventful, and that the performance of the helicopter was "good," with no problems noted. Comparisons between the width of the trailer, and the width of the landing gear skids revealed that a landing centered on the trailer left only 9 inches of platform on the outside of each skid. The pilot had accrued about 210 total hours of flight experience, all of which was in helicopters. He had about 100 total hours of experience in make and model, approximately 90 hours of which were in the accident helicopter.
NTSB Probable Cause Narrative
The pilot's failure to maintain control while landing to a trailer, which resulted in a collision with terrain. A factor in the accident was the narrow trailer.
