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 rnwy 20R. Shortly after rotating, pitched steeply up followed by a stall then steep pitch down impacting the ground at about a 45 degree nose down attitude. Aircraft came to a stop on the median between the runway and taxiway. Fuselage broke in two behind rear bulkhead. Right wing impacted the runway. Left wing impacted the grassy area where the aircraft came to rest. Pilot had the trim wheel slightly nose up but not abnormal. Pilot stated during the preflight control check the controls responded appropriately. Pilot stated he pushed as hard as he could on the yoke, but the nose would not come down. Further investigation revealed an instrument vacuum hose was laying across the control column potentially restricting the movement of the flight control column.
