Probable cause
The pilot's inadequate compensation for wind conditions during the takeoff roll, which resulted in a loss of directional control and a nose over.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
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.
