Accident Overview
An agricultural aircraft (ACFT) was conducting swath runs as part of an aerial application operation. After completing two swath runs, the aircraft entered a procedure turnaround over a wooded area. During the maneuver, the engine lost power. The pilot attempted to glide the aircraft to a suitable landing area, but the aircraft struck the tops of trees and subsequently crashed.
Pre-Accident Background
According to the aircraft owner, the engine had a history of maintenance problems prior to the accident. However, no specific problem had been identified before the flight.
Post-Accident Investigation
Following the accident, the engine was disassembled at an overhaul facility for examination. Investigators found no evidence of preimpact or mechanical failure. The ambient temperature at the time was 82 degrees Fahrenheit, with a dew point of 75 degrees Fahrenheit.
Conclusion
The investigation did not identify a specific mechanical cause for the engine power loss. The aircraft's collision with trees and subsequent crash resulted from the inability to maintain flight after the power loss.
