On November 29, 1991, a Cessna 421B (registration N421DP) operated by Stanford P. Kibbe was involved in an aviation accident near San Andreas, CA. Investigators recorded the probable cause as: The pilot's failure to remove the control column's elevator gust lock due to not following the checklist closely during the night preflight inspection. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a night preflight, the pilot did not follow the checklist closely and failed to remove the elevator gust lock. During takeoff roll, he felt the lock and aborted, but insufficient runway remained, causing an overrun into a fence.
