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) The purpose of the instructional flight was for insurance purposes for the second pilot to get 1 hour in the CE-140 with an instructor. After 6 good touch and go's it was decided the 7th landing would be to a full stop. The second pilot was on the controls and stated that as he applied the brakes he sensed the wheels were slipping and intermittently sliding on the contaminated runway 35. There had been numerous snow storms in the vicinity in recent days. The runway was not completely clean and dry. There were patches of standing water, slush and some snow and icy patches. The pilot stated that as he was preparing to exit at the next taxiway, with some brake still applied, the wheels encountered an unforeseen dry patch and with brakes applied, the aircraft suddenly flipped upside down onto its back. Prior to this event the aircraft was under control. An on-site inspection of the runway and the personal observations of an ASI who, the day before, confirmed poor runway conditions, it was determined the event could very well have occurred as described by the experienced and competent pilot at the controls.
