Aircraft Accident/Incident Report
Wilsonville, Oregon 97070
Wednesday, February 9, 2011 12:55 PST
NTSB Narrative Summary Released at Completion of Accident
According to the pilot, he took off from the airport in his amphibious experimental airplane with the intention of flying a closed traffic pattern. Because he planned to land back on the runway, he left the landing gear in the extended position. During departure, he overflew a river, located about 3 miles north of the airport, and observed that the water was calm. The pilot stated that he made a spur of the moment decision to land in the river, and he forgot that the wheels were extended. The airplane was not equipped with an aural gear warning horn or gear position lights; however, it was equipped with mirrors on each wing in which he could have visually determined the position of the gear. The pilot stated that he did not check the position of the gear with the mirrors. He indicated that he forgot to raise the gear prior to landing in the water. Consequently, the airplane nosed over as it decelerated. During this event, a portion of the lower engine cowl broke, and most of the front windscreen separated from the cockpit. The pilot reported that he did not experience any malfunction with the airplane.
NTSB Probable Cause Narrative
The pilot's failure to raise the landing gear wheels prior to landing in water, resulting in a nose over.
