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.

Became loaded with ice during IFR flight. Hard side load impact on landing collapsed the gear. Crosswind a factor. (.4) the pilot said the airplane encountered freezing rain that was changing to snow as the airplane broke out of the clouds at 600-feet above ground level during an ILS approach. He said the airplane had about 3/8 to 1/2-inch of ice on its airframe. According to the pilot, the airplane touched down on its left main landing gear, as he landed at dusk with a 10-knot left quartering tailwind. He said the left main gear tire rolled off its wheel as the nose gear and right main landing gear contacted the runway. Both the right main and nose landing gear collapsed. The pilot said he landed in a slight crab at touchdown on the ice-covered runway. The pilot said the windshield was ice covered with a clear area of about 8-inches by 11-inches through which he could see. (-23) after picking up ice on ILS35, pilot side loaded the gear during a crosswind landing and collapsed the gear.
