Probable cause

The failure of the left main landing gear on landing for reasons that could not be determined due to the extent of damage sustained during the accident.

NTSB narrative

The commercial pilot stated that he confirmed that the landing gear were down and locked before landing. After a smooth landing, the left wing began to sink. The pilot shut off the left engine, and the airplane veered left off the runway onto grass. The pilot then shut off the right engine. The left wing, left horizontal stabilizer, and left propeller assembly were substantially damaged. Examination of the left main landing gear (MLG) revealed that the fork bolt was ripped out of the torque tube, which damaged the tube and precluded a gear retraction test. Visual examination of the left MLG revealed that the overcentering tension on the down-lock assembly appeared to be rigged incorrectly; however, it could not be determined if the misrigging led to the failure of the left MLG. A review of the airframe maintenance logbooks revealed no recent maintenance to the MLG assembly. Based on the available evidence, the reason for the left MLG collapse could not be determined.
