NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of the tailwheel-equipped airplane reported that, after conducting two touch-and-go landings at a nearby airport, he decided to land at a different airport to speak with a friend. He added that everything seemed normal during the touchdown on the snow-covered runway but that the airplane then “abruptly stopped and [nosed] over.” 

The airplane sustained substantial damage to both wings and the rudder.

The pilot reported that the inside of the left main landing gear and brake was “packed with ice” and had frozen, which prevented the wheel from rotating during the landing roll.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The contamination of snow and ice on the left main landing gear and brake, which prevented the wheel from rolling during touchdown and resulted in a nose-over.
