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.

Aircraft departed to the left of runway 27 and came to rest at airport boundary fence and ditch that runs parallel to the fence. Nose wheels were buried in the side of the ditch, turned to the left approximately 35 degrees from center. Tire marks in the grass and the position of the aircraft indicate that as the aircraft slowed that the turn rate increased. Interviewed captain, captain stated that when he placed the power levers in to beta range that the aircraft was turning to the left, he applied right brake, with no anticipated response, he applied full reverse on the right engine and more right braking with no anticipated response to bring aircraft back to center, while pushing the control master switch for steering disengagement. Upon leaving the runway he applied full braking and full reverse on both engines, the aircraft left wing struck a tree causing substantial damage and the forward canard left side struck the ground and fence causing substantial damage to the canard and structural mounting. The nose gear doors were damaged from impact with the side of the ditch, the radome was damaged from ground impact and impact with a fence pole.
