Aircraft Departed Runway After Landing in Freezing Fog (N74RQ)

Approach and Missed Approach Procedure The captain reported that the crew had flown a GPS approach to runway 35. Because the runway and its environment were not visible, the crew initiated a missed approach. During the missed approach, the crew observed the first 4,000 to 5,000 feet at the approach end of runway 17. The captain stated that they elected to circle to the northwest to set up for a visual approach to runway 17. ## Landing and Runway Departure The captain described the approach as slightly high, resulting in a flare that was higher than normal. The airplane entered a fog layer just prior to touchdown. During the landing flare, the captain stated that the airplane had drifted to the left. The aircraft settled onto the runway to the left of the centerline, and shortly thereafter, the left main gear impacted a snow berm. The airplane then turned hard to the left and departed the runway. ## Damage and Weather Conditions The nose gear separated, the radome was crushed, and the cockpit pressure bulkhead was broken open. The routine aviation weather report (METAR) at LGU reported the following conditions: wind calm; visibility 1/4 statute mile in freezing fog; sky condition vertical visibility 100 feet above ground level; temperature minus 7 degrees Celsius; dewpoint minus 7 degrees Celsius; and altimeter 30.45 inches.
