On August 29, 1995, a Cessna 310K (registration N6921L) was involved in an aviation accident near Columbiana, OH. Investigators recorded the probable cause as: The improper maintenance installation and the subsequent separation of the torque links on the left main landing gear during the landing roll. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Incident
During the landing roll, the pilot reported feeling a drag on the left side of the aircraft, which caused the airplane to veer sharply to the left. The aircraft departed the left side of the runway and struck trees located approximately 150 feet to the left of the landing surface.
Post-Accident Examination
A postaccident examination of the aircraft revealed that the washer under the left landing gear torque link attachment bolt head was not installed. The torque links had separated. The pilot stated that the airplane had just received maintenance to repair a previously failed torque link.
Summary of Events
The incident occurred during the landing phase when the aircraft unexpectedly veered left and exited the runway. The subsequent examination identified the missing washer and separated torque links on the left landing gear.
