Aircraft Accident/Incident Report

Bowstring, Minnesota 56680
Sunday, July 17, 2005 13:45 CDT

NTSB Narrative Summary Released at Completion of Accident

The fixed-float equipped airplane sustained substantial damage when it nosed over during an aborted takeoff in rough water. The pilot reported that by the time he arrived the lake was "rough" and the tie downs were not holding. He stated that during the takeoff run he decided that it was "too rough to continue." He reported that he "let up" on the throttle and was slowing down, when the left float "caught a wave" and the airplane nosed over. Wind conditions recorded by the Bigfork Municipal Airport (FOZ) Automated Weather Observing System (AWOS), located 18 nautical miles northeast of the accident site, at 1335, were from 170 degrees at 19 knots, gusting to 27 knots. The pilot reported winds from 140 degrees at 18 knots, gusting to 22 knots. The pilot stated that there were no failures or malfunctions with the aircraft prior to the accident.

NTSB Probable Cause Narrative

The unsuitable water conditions for takeoff selected by the pilot and his inability to maintain aircraft control in the rough water. Contributing factors were the aborted takeoff initiated by the pilot, the rough water conditions and the high, gusty winds.
