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 was taxiing aircraft to parking in front of FBO. Braking was insufficient to stop aircraft. Aircraft continued forward motion as pilot mismanaged power/prop controls. Aircraft travelled approximately 170 feet from intended parking to impact with hangar structure. Brakes were inspected and master cylinders were found to be empty of fluid. Aircraft sustained substantial damage to left wing and both props.
