NTSB Factual Report

The pilot of the amphibious float-equipped airplane reported that, during landing touchdown on a paved runway, the airplane encountered a wind gust and the airplane became airborne. The pilot added full power to go around, but the left wing aerodynamically stalled and the left float struck the runway, resulting in a cartwheel.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation station, located 11 miles west of the accident airport, reported that, about the time of the accident, the wind was from 040° at 7 knots. The airplane landed on runway 8.

NTSB Probable Cause

The pilot’s exceedance of the airplane’s critical angle of attack during a go-around.
