Probable cause

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

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the airplane reported that, during touchdown on a paved runway, the airplane encountered a wind gust and then became airborne. The pilot added full power to go around, but the left wing aerodynamically stalled, and the left float struck the runway, which resulted 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.
