On June 11, 2007, a Piper PA-12 (registration N78492) was involved in an aviation accident near Koyukuk, AK. Investigators recorded the probable cause as: The pilot's inadequate compensation for a gusting tailwind during the landing roll, which resulted in a loss of control and a nose over. Factors contributing to the accident were the tailwind and wind gust. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A tailwheel-equipped aircraft was damaged after rolling onto its back during a landing attempt on a mountain ridge, resulting in damage to the wings and rudder.
What happened
The pilot, holding an airline transport certificate, attempted to land a tailwheel-equipped airplane on a mountain ridge under Title 14, CFR Part 91. The pilot reported that landing uphill required landing with a tailwind. During the landing roll, a gust of wind picked up the tail and rolled the airplane upside down. The pilot said the airplane sustained damage to both wings and the rudder.
