Incident Summary
A pilot reported diverting from the intended destination after discovering a partially open cabin door. Upon arrival at the diversion airport, the aircraft entered the traffic pattern and prepared for landing on a 2,690-foot runway with a 600-foot displaced threshold.
Sequence of Events
During the short final approach, a high sink rate developed. The pilot applied nose-up elevator input three times, but engine power was only increased during the third input. The aircraft subsequently landed hard on the right main landing gear, causing it to collapse.
Landing and Aftermath
Following the collapse of the right main gear, the airplane bounced twice, veered off the right side of the runway, and contacted a closed taxiway that was raised 4–6 inches above the surrounding surface. This impact caused the left main landing gear and the nose landing gear to collapse as well. No further details were provided regarding occupants or injuries.
