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.

The road is not on airport property and is separated from the airport environment by a fence. From the impact damage on the truck the aircraft was approximately 13 feet above the ground when it struck the trailer. The road has two gates and red blinking lights at each gate to warn vehicular traffic of approaching aircraft.
