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) During roll out after uneventful landing the tailwheel commenced to shimmy and shake. Pilot added power and attempted to lift tail to relieve the tailwheel shimmy/shaking. This aircraft has dual-puck disc brakes which are extremely powerful, combined with added power and the short coupling (distance between the main landing gear and the tailwheel) make the aircraft sensitive to rudder/brake application. Rudder and brake inputs contributed to this aircraft departing the runway into the grass. After departing the runway the right tailwheel steering spring came off the aircraft which left limited rudder/tailwheel steering authority. Uneven application of the brakes and forward momentum allowed the aircraft to yaw to the right causing the left main landing gear to fold under and collapse.
