NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

While attempting a water landing, the amphibian airplane impacted the water in a nose-low attitude and nosed over into the water after a second impact with the water. The pilot reported that the airplane impacted the wake of a speedboat that had crossed beneath the airplane during final approach. The passenger reported that the pilot told him that he "stalled the airplane" during landing. The passenger's daughter recorded the accident on videotape. A review of the videotape showed the airplane making a low altitude, level turn toward video camera. The recorded engine noise was consistent with an idle engine power setting. The airplane transitioned to a nose-down attitude and impacted the water. The recorded engine noise increased after the airplane transitioned to the nose low attitude. The airplane bounced off the water and nosed over after a second impact with the water. There was no evidence of a speedboat or rough water around the accident airplane during the accident sequence.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain appropriate airspeed during landing, which resulted in a stall/mush condition and hard landing.
