Probable cause

The retraction of the left main landing gear after landing for reasons that could not be determined during postaccident examinations.

NTSB narrative

The pilot reported that, after departure, he noticed that the landing gear did not retract as usual. He began to troubleshoot the problem and actuated the gear-down lever. The landing gear did not extend, and the green landing gear light in the cockpit did not illuminate. He recycled the landing gear, but the gear still did not extend. The pilot continued to the destination airport and asked an air traffic controller to observe the position of the landing gear. The controller reported that the gear appeared to be down and cleared the flight to land. During the end of the landing roll, the left landing gear retracted, which resulted in substantial damage to the left wing spar. Postaccident examination of the airplane revealed that the landing gear compartment was dirty and covered in oil and debris. However, the examination did not reveal the reason for the landing gear retraction.
