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) Pilot applied takeoff power, released brakes and started takeoff roll on runway 35 at angle Fire, NM airport (axx). At bottom of white arc, pilot pulled yoke back to start rotation. Aircraft deviated to left, pilot applied right rudder to correct, but aircraft continued to left, leaving runway surface at approximately 2100 feet down the runway. Pilot applied more nose up elevator to try and clear a ditch between runway and taxiway. Left main gear contacted dirt surfacce on FAR side of ditch breaking main gear off. Aircraft continued across dirt surface, across ramp and tiedown area, off ramp and down into grass area finally contacting a fence which brought aircraft down. Pilot stated he began pulling yoke aft at bottom of white arc (75), no VMC marked on airspeed indicator, but vyse marked at (112). Torque and "p" factor with nose wheel up at well below vyse with density altitude computed to be at 9945' led to deviation to the left that was uncontrollable with rudder.
