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) According to the pilot, during landing on a snow covered lake with his ski equipped Cessna 180, the following occurred. When the left ski contacted the snow covered lake, the aircraft yawed sharply. The yaw effect placed excessive side-load on the ski and landing gear instantly decelerating the aircraft speed. The quick deceleration and side-load caused the aircraft to nose over on its top. Left wing, vertical stabilizer and rudder damage occurred when the aircraft noseed over on its top. After the accident, the pilot conducted a survey of the landing area. He found indications that the left ski struck an ice pressure ridge hidden by freshly fallen snow.
