Probable cause
The pilot’s misjudgment of the approach and his subsequent exceedance of the airplane’s critical angle of attack during an agricultural application flight, which resulted in an aerodynamic stall and collision with power lines.
Findings · 4
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 misjudged the approach and did not have enough clearance to avoid power lines. The airplane began to sink, and he pulled back on the flight control stick. Subsequently, the airplane aerodynamically stalled and then struck power lines. The airplane sustained substantial damage to the fuselage, empennage, and both wings. 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 misjudged the approach and did not give enough clearance for power wires. The airplane began to sink and he pulled back on the flight control stick. Subsequently, the airplane aerodynamically stalled into the power wires. The pilot further reported that he did not remember anything else until he awoke in the hospital. The airplane sustained substantial damage to the fuselage, empennage, and both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
