On February 23, 1993, a Cessna A185F (registration N37BC) operated by Williamson, Ken R. was involved in an aviation accident near Fairbanks, AK. Investigators recorded the probable cause as: Incorrect replacement of the fuel valve placard, causing the fuel valve to be in the OFF position when selected to BOTH. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During initial climb, the engine lost all power, forcing a 180-degree turn and landing on the unplowed portion of the Chena Marina Strip. After landing, the elevator balance tab struck ice and was torn in half. Investigation revealed a mislabeled fuel valve placard.
Accident Overview
During the initial climb out, the engine lost all power. The pilot executed a 180-degree turn and landed on the unplowed portion of the Chena Marina Strip.
Forced Landing and Damage
After the landing and during the rollout, the elevator balance tab struck a piece of ice and was torn in half.
Investigation Findings
Examination of the airplane showed that the fuel valve placard was replaced incorrectly. When the fuel valve was placed in the BOTH position, as required for takeoff, the valve was actually in the OFF position. The airplane had just received a new interior which had been installed by an uncertificated individual. The airplane was not inspected, nor were there any entries in the logbook showing the new upholstery work.
Probable cause
Incorrect replacement of the fuel valve placard, causing the fuel valve to be in the OFF position when selected to BOTH.
