Aviation Accident Summary ANC19CA057

Arctic Village, AK, USA

Aircraft #1

N7056D

Piper PA22

Analysis

According to the pilot, he was conducting a low-reconnaissance flight over a mountain ridgeline to determine its suitability as an off-airport landing site. The pilot stated that he was not paying attention to the airspeed as he completed the flyover and approached rising terrain. To avoid the rising terrain, he applied full power and turned left, but the right wing stalled while the airplane was about 20 ft above ground level, and then it struck terrain. The airplane cartwheeled, which resulted in substantial damage to the right wing and fuselage. The pilot stated that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

According to the pilot, he was conducting a low reconnaissance flight over a mountain ridgeline to determine its suitability as an off-airport landing site. The pilot stated that he was not paying attention to the airplane's airspeed as he completed the flyover and approached rising terrain. In an effort to avoid the rising terrain, he initiated a go-around by applying full power and starting a left turn, but the right wing stalled and struck terrain. The airplane cartwheeled sustaining substantial damage to the right wing and fuselage. The pilot stated there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.
