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.
(-23) Upon landing the aircraft encountered a wake from a passing vessel. The aircraft then started to porpoise, eventually hitting the wake so hard as to cause the pontoon struts to fail, thereby allowing the propeller to come in contact with and cause damage to the pontoon.
