Probable cause
The pilot's exceedance of the airplane's critical angle of attack during a low-altitude turn, which resulted in an aerodynamic stall.
Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that, during an agricultural application flight, he stalled the airplane while in a low-altitude turn. In an attempt to recover, the pilot dumped the chemicals, but the airplane continued to descend and impacted a hillside. The airplane sustained substantial damage to the fuselage and engine mounts. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Factual narrative
The pilot reported that during an aerial application flight, he stalled the airplane while in a low altitude turn. In an attempt to recover, the pilot jettisoned the chemicals, but the airplane continued to descend and impacted the hillside. The airplane sustained substantial damage to fuselage and engine mounts. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
