Background
A pilot initiated takeoff during early morning hours, with a witness describing the conditions as still dark. The departure point was at a lower elevation compared to the accident site. The operator noted the pilot's tendency to handle equipment gently and reduce throttle shortly after takeoff.
Sequence of Events
After becoming airborne, the pilot reduced engine power. The engine was reported to sound normal until the aircraft collided with trees. At some point during the incident, the pilot jettisoned the load. There was no wind present at the time.
Operator Observations
The operator stated that the pilot likely fell behind the power curve without realizing it. The aircraft maintained normal engine operation until impact.
Findings
The accident involved a takeoff in dark conditions, a subsequent throttle reduction, and a collision with trees on terrain higher than the departure point. The load was dumped before impact.
