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 stated that he was performing a water landing in a cove with gusty wind conditions. The airplane touched down twice and, on the third touchdown, veered violently to the left. He believed that he either “chined and waterlooped” or that the left sponson contacted the water first. Both sponsons and the left wing tip were substantially damaged. Additionally, the left side of the airplane’s nose and left fuselage at the pilot entry station were wrinkled and bent.

Factual narrative

The pilot stated that he was performing a water landing and believes the left sponson contacted the water about the same time as the hull. The airplane water-looped, bending both sponsons and the left wing tip. Additionally, the left side of the airplane’s nose and left fuselage at the pilot entry station were wrinkled and bent.
