On October 8, 1982, a Cessna 206 (registration N5183U) operated by Linn Air Service was involved in an aviation accident near 40 NM Wnw Salmo, ID. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during takeoff on a runway covered with wet snow and slush, which resulted in the aircraft veering off the runway. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.
An aircraft departed the runway and sustained damage after veering into deep snow during takeoff from a slush-covered runway at high elevation.
What happened
The pilot initiated a takeoff roll on a runway surface covered with approximately six inches of wet snow and slush. Wind conditions were calm at the time of departure. During the acceleration phase, the right main landing gear settled back onto the runway surface and encountered an area of soft snow and slush. This interaction caused the aircraft to veer to the right into deeper snow accumulations. The aircraft subsequently departed the runway and sustained damage.
The investigation
The airport elevation was recorded at 7,030 feet. No mechanical failures or maintenance discrepancies were identified in the provided narrative. The primary factor was the interaction between the landing gear and the contaminated runway surface.
Probable cause
The pilot's failure to maintain directional control during takeoff on a runway covered with wet snow and slush, which resulted in the aircraft veering off the runway.
