Event Summary
The airplane was returning to land after the entry door opened during takeoff. On the landing attempt, the airplane touched down on sandy soil approximately 30 feet before the approach end of runway 25. Upon contacting the runway surface, which was about 3 inches higher than the preceding terrain, the right main gear was forced sideways. The airplane continued onto the runway, and the right main gear collapsed roughly 400 feet past the approach end. Subsequently, the airplane departed the right side of the runway and came to rest.
Sequence of Events
According to an inspector's statement, the pilot was returning to the airport due to the door opening event. The undershoot landing resulted in initial contact with sandy soil short of the runway. The runway's elevation difference of approximately 3 inches relative to the terrain caused the right main gear to cock sideways. The gear failure occurred as the airplane traveled further along the runway. After the collapse, the airplane exited the runway to the right and stopped.
Examination Findings
The right main gear collapsed after the airplane had traveled about 400 feet on runway 25. The inspector noted that the gear cocked sideways upon impact with the runway edge. No further details on damage or injuries were provided in the source.
