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.

Pilot had landed on a large gravel bar in the Susitna River at the confluence of the Susitna River and yentna River. Afterward, pilot elected to land on a short gravel bar and did a pass to look at it and then turned in close to land, and on short final aircraft descended and impacted in the River water, significantly short of the intended landing spot on the gravel bar. Pilot stated the water was shallow, but the aircraft had flipped completely over onto its back, and the pilot and his passenger exited the upside-down aircraft into the shallow River water and walked to shore. Pilot stated to FAA iic he thinks he likely stalled the wing, and may have flown through his own wake, causing a shift in relative wind and a loss of lift. Pilot also stated he has quite a bit of time in this airplane, but not since the wing was recently repaired, after it was damaged while parked at lake hood strip by another aircraft impacting it. Pilot also discussed regaining familiarity with his privacy data omitted after flying larger aircraft for an air carrier, before attempting to operate from small confined off-airport locations.
