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.

(.4) The wing of the glider struck a tree when the solo student pilot was correcting the flight path to align the glider with the runway centerline during the final approach. The density altitude was calculated at 4,215 feet. The student pilot had 15.2 hours of total flight time in gliders. He was endorsed for solo flight and had 2.4 hours of solo flight time in the glider. The operator reported that the accident could have been prevented by `maintain[ing] adequate clearance over obstacles.'
