On September 20, 1982, a Cessna U206F (registration N9530G) operated by Fred Toten was involved in an aviation accident near Baton Rouge, LA. Investigators recorded the probable cause as: The roll pin (PN NAS561P3-6) had fallen out of the yoke (PN HE 1328), allowing slippage between the fuel selector handle and valve, resulting in the selector valve rotor being in the off position, which caused the engine failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
While descending through 2200 ft MSL, the pilot moved the fuel selector from right to left, resulting in immediate engine failure. Repeated restart attempts were unsuccessful, and the aircraft landed in a residential yard. Examination found a missing roll pin in the fuel selector system.
Incident Details
The pilot was descending through 2200 ft MSL when they changed the fuel selector position from right to left. Immediately after moving the selector, the engine failed. Despite multiple attempts to restart the engine by changing the fuel selector position, the engine could not be restarted. The aircraft subsequently landed in the yard of a residence.
Investigation Findings
An examination of the fuel selector system revealed that the roll pin, part number NAS561P3-6, had fallen out of the yoke, part number HE 1328. This allowed slippage between the fuel selector handle and the fuel selector valve. The selector valve rotor was found in the off position, indicating that the valve was not properly aligned with the handle position.
Probable cause
The roll pin (PN NAS561P3-6) had fallen out of the yoke (PN HE 1328), allowing slippage between the fuel selector handle and valve, resulting in the selector valve rotor being in the off position, which caused the engine failure.
