Summary
On June 24, 2007, a Grumman G21A (N7811) was involved in an incident near Dutch Harbor, AK. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's inadequate compensation for wind conditions during the takeoff roll, which resulted in a loss of directional control and a nose over.
The pilot had dropped off passengers, and was taking off to return to the base airport under Title 14, CFR Part 91, when the accident occurred. The pilot said he was departing on a hard surface runway in an amphibious, tailwheel equipped airplane. He said after the tailwheel lifted off, he believed a quartering gust of tailwind pushed the airplane off the runway. He said he tried to maintain directional control, but the airplane's right main landing gear encountered a tundra mound, and the airplane nosed over. The pilot said the right wing separated from the airplane during the accident. There were no known mechanical anomalies with the airplane prior to the accident.
This incident is documented in NTSB report ANC07CA053. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N7811.
