NTSB Factual Report

The pilot reported that he was giving a promotional ride in conjunction with an upcoming airport open house. At the time of the accident, he was conducting a flour bomb drop demonstration. The pilot stated that on the third approach he became distracted and was not fully paying attention to flying the airplane. The airplane got too low and too slow on the approach, and inadvertently stalled. The pilot reported that there were no failures or malfunctions associated with the airplane prior to the accident.

NTSB Probable Cause

The pilot’s failure to maintain sufficient airspeed during a low approach, which resulted in an aerodynamic stall.
