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 was on vor/dme-c approach in IFR, inbound for landng. Controllers reported wind 180 at 10 gusting to 16, field was IFR, visibilty 2.5 miles, rain, wet runway. Pilots choice of runways, no other traffic. Pilot elected to land runway 30 with a tailwind component of 8 knots on a very wet runway. Runway length is 6600' tower witness aircraft touch down at A-6 which is 1900' from threshold. Pilot reported ineffective braking action upon landing. Elected not to risk going around. Next communication was aircraft off end of runway. During interview PIC and SIC provided landing distance of 3600 feet dry runway and 5100 feet wet runway. At touchdown the aircraft had 4700 feet of runway remaining. 200 feet of paved overrun and another 200 feet of grass before a ditch. Aircraft sustain substanial damage when the nose gear impacted the ditch, breaking off the nose gear strut assembly and nose gear actuator. Which damaged the forward pressure bulkhead, forward lower pressure vessel as the aircraft continued to slide nose on ground and over gear assembly.
