Sequence of Events
The airplane was conducting a precision instrument approach and landing on runway 29. Night visual meteorological conditions prevailed at the time. After touchdown, the airplane moved "quickly" to the left, departed the side of the runway, and entered snow. The nose wheel landing gear folded during the event.
Weather Information
The pilot stated that the airport's automated weather observing system (AWOS) reported calm winds. However, the pilot considered this inaccurate and checked reports from surrounding AWOSs, which indicated winds from the northwest at 8 to 11 knots. The maximum demonstrated crosswind for the airplane is 17 knots.
Post-Accident Inspection
Following the accident, inspection of the airport's AWOS revealed that the unit was covered with ice, which inhibited operation of the wind speed and direction sensors. The Federal Aviation Administration had no record of a Notice to Airman (NOTAM) being issued on the day of the accident pertaining to the airport AWOS.
