Aviation Accident Summary WPR11CA128

Buttonwillow, CA, USA

Aircraft #1

N6725K

SCHWEIZER G-164B

Analysis

The pilot stated that he was making a low aerial application pass over a field, dispensing smoke to determine wind direction and velocity. The airplane struck a 20-foot-high irrigation vent pipe, which was located in the field that he was working. He proceeded straight ahead and attempted a forced landing on a dirt road immediately next to the field because the engine was losing power. Upon touching down, the right main wheel encountered soft dirt and the airplane nosed over inverted, bending the engine mount and wrinkling the fuselage and vertical stabilizer.
