The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he entered the traffic pattern and completed the before landing checklist, including lowering the flaps and landing gear. He further reported that there were no anomalies, and the landing was uneventful until the right main landing gear collapsed during the landing roll. The airplane departed the right side of the runway, the nose and left main landing gear collapsed, and the airplane came to rest on its belly. Postaccident examination revealed impact damage to the inboard right main landing gear door that was consistent with the door being partially open when the damage was sustained. Because the inboard gear doors are closed when the landing gear is in the down position, the partially open position of the gear door indicates that the right main landing gear was not down and locked. No evidence was found of preimpact broken or disconnected parts in the right main landing gear extension/retraction mechanism. Impact damage to the landing gear precluded performance of a landing gear extension/retraction test, and the reason for the right main landing gear collapse was not determined.
