Probable cause

The pilot’s failure to maintain proper airspeed and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.

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 departed from a river sand bar, and shortly after takeoff the airplane encountered an unexpected left quartering tailwind. The pilot reported that the airplane’s left wing stalled, which induced a spin at a low altitude. The airplane’s left wing and forward left fuselage impacted the shallow river water and sustained substantial damage. Since the accident, the airplane washed away in the river current and has not been located. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
