Probable cause

The pilot did not secure the manual landing gear operating handle, which resulted in the landing gear collapse during the landing roll.

NTSB narrative

The pilot said that he completed the landing checklist, which included putting the landing gear down, while on the downwind leg for landing and that he made a final check of the landing gear handle, mixture, and propeller controls while on final approach. The approach and touchdown were normal, but, during the landing roll, the airplane came to a sudden stop on its belly. Postaccident examination revealed that the Johnson bar operating handle for the manual landing gear system was not in the fully locked position. Therefore, the landing gear was down but not locked into position during touchdown, and it subsequently collapsed during the landing roll.
