What happened
Witnesses observed the aircraft executing a descending, low-level turn at the conclusion of a pesticide application run. Immediately following this maneuver, the aircraft nosed over and dove directly into the soybean field that was being treated.
At the time of the accident, the pilot was not wearing a shoulder harness or a helmet. Subsequent toxicology analysis revealed low levels of cholinesterase in the pilot's blood. The chemical agent being applied during the flight was methyl parathion, which is known to act as a cholinesterase inhibitor.
The investigation
Investigators examined the circumstances surrounding the crash and the physiological state of the operator. The focus included the specific actions taken during the final phase of the spray run and the presence of inhibiting chemicals in the pilot's system.
Findings
The sequence of events indicates a loss of control during a critical low-altitude maneuver. Contributing factors included the failure to utilize mandatory safety equipment, specifically the shoulder harness and helmet. Additionally, the presence of methyl parathion, a cholinesterase inhibitor, in the pilot's blood suggests potential physiological impairment affecting operational performance.
Safety message
Operators conducting aerial application must strictly adhere to personal protective equipment requirements. Wearing a shoulder harness and helmet is essential for safety during low-level flight operations.
