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.

On 6/24/2018 at 1630 MDT, N963CG sailplane crash landed in a hayfield near parowin, UT (1L9). Pilot reported a loss of lift and thermal activity while maneuvering. Pilot stated the thermal lift was not particularly strong and the sustainer engine although certified to 10 thousand feet was known for reliability issues at higher density altitudes and restart was unsuccessful. At 8500 feet still in sinking air, the pilot committed to selecting a field for landing. The right elevator/horizontal stablilizer sustained substantial damage during the landing roll and subsequent ground loop.
