From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.
What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: while taxiing out, the aircraft encountered a large wave that washed over the right float. The aircraft tipped right and nosed down causing the right wing to hit the wave, which inverted the aircraft. The pilot exited the aircraft without injury. There were no other souls onboard. There was no damage, other than water damage to the aircraft.
