What happened
The pilot was conducting agricultural spraying operations when the incident occurred. After completing his fourth pass, he executed a turn over a wooded area. During this maneuver, the engine power unexpectedly dropped to idle RPM. Unable to maintain altitude or continue the flight, the pilot was forced to land in the trees adjacent to the field he was servicing.
The investigation
A post-acc examination of the aircraft revealed no preimpact mechanical failure that could account for the loss of power. The investigation focused on the engine's performance and the pilot's recent experience with the specific make and model of the aircraft.
Findings
The primary factor contributing to the accident was the pilot's limited familiarity with the aircraft. Records indicated that the pilot had only 1 hour of previous flight experience in this specific make and model. This lack of experience likely contributed to the inability to manage the situation effectively when the power loss occurred.
Safety message
Pilots operating in specialized roles such as crop dusting should ensure they have sufficient proficiency in their aircraft before undertaking complex maneuvers. Limited experience in a specific make and model can significantly increase risk during unexpected events.
