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.

(-23) on October 15, 1997, at approximately 1800 central, a Grumman G-164A, N8819H, sustained substantial damage during a forced landing near Altus, OK. No injuries were reported. The pilot reported that the aircraft engine lost power as he was turning the aircraft between spray passes. The pilot made a forced landing in a soft field, and the aircraft nosed over and came to rest inverted. The aircraft sustained substantial damage to the top wing and vertical stabilizer.
