What happened
The pilot was conducting agricultural crop dusting operations, having completed several spray swaths prior to the incident. During the execution of another right turn to initiate a new spray swath, the aircraft unexpectedly entered a left descending turn. The flight path intersected with nearby trees, leading to a crash. Following the impact, the aircraft caught fire.
The investigation
A thorough examination of the wreckage was conducted to determine the mechanical status of the aircraft. Investigators found no evidence of pre-impact mechanical failures or malfunctions with either the airframe or the power plant. Physical evidence recovered from the accident scene indicated that the propeller was rotating at a low RPM at the time of impact.
Findings
The investigation revealed that the aircraft's structural integrity and engine performance were not compromised prior to the crash. The primary finding related to the flight dynamics involved the unexpected change in turn direction and descent during a routine maneuver. The low propeller rotation speed observed at the scene suggests a potential issue with power delivery or pilot input, though no mechanical cause was identified.
