Probable cause
The pilot's inadvertent use of the parking brake. A factor contributing to the accident was the absence of the parking brake on the landing checklist.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The amphibious aircraft had been landed on the lake and moored close to shore in shallow water. The pilot had set the parking brake with the wheels extended to stabilize the aircraft at the mooring site. Subsequently, the aircraft was repositioned to a nearby airstrip. The parking brake was not disengaged prior to the touchdown and the aircraft nosed over during the landing roll. The operator's manual did not address the possibility of landing with the parking brake engaged.
