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 airplane experienced a main gear collapse following an undershoot landing. The pilot was returning to land after the aircraft's entry door opened on takeoff. The inspector stated the airplane touched down on sandy soil approximately 30 feet prior to the approach end of runway 25. He stated the right main gear cocked sideways when the airplane contacted the runway which was approximately 3 inches higher then the terrain. The airplane continued onto the runway and the right main gear collapsed approximately 400 feet past the approach end of the runway. The airplane then traveled off the right side of the runway where it came to rest.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's misjudged distance/altitude which resulted in an undershoot. A related factor was the pilot's diverted attention due to the open cabin door.
