Summary

On August 10, 2006, a Piper PA-12 (N7663H) was involved in an accident near Coldfoot, AK. The accident resulted in 1 minor injury, with 1 person uninjured out of 2 aboard. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's selection of an unsuitable landing area, which resulted in an in-flight collision with terrain during an aborted landing. Factors associated with the accident were wind gusts, and rough and uneven terrain.

The private pilot was landing on a mountain ridgeline in a tundra tire-equipped airplane during a Title 14, CFR Part 91 business flight. The pilot said that he inadvertently touched down about 10 feet beyond his intended touchdown point, and he added full engine power to abort the landing. After becoming airborne, a gust of wind pushed the airplane towards the ground, and the right main wheel struck a large rock. The airplane collided with the ground, and the main landing gear collapsed. The airplane sustained structural damage to the wings, fuselage, and empennage. The pilot noted that there were no preaccident mechanical anomalies with the airplane.

This accident is documented in NTSB report ANC06CA110. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N7663H.
