| Confidence Rating: |  Accident investigation report completed and information captured |
The passenger reported that the pilot was maneuvering the helicopter over an area of tree-covered marsh at a low altitude when the helicopter entered a descent, collided with trees, and impacted the ground on its left side. An examination of the wreckage found damage consistent with the main rotor blades being driven by the engine when they contacted the trees. Although the passenger reported hearing a loud sound before the helicopter started descending, postaccident examination of the helicopter revealed no evidence of preimpact mechanical malfunction or failure that would have precluded normal operation. The circumstances of the accident are consistent with the pilot failing to maintain altitude while maneuvering at low airspeed and low altitude, which resulted in the helicopter descending into trees.
Probable Cause: The pilot's failure to maintain altitude while maneuvering, which resulted in a collision with trees. Contributing to the accident was the pilot's decision to fly at a low altitude, which did not provide enough margin to recover from the descent.
