Aircraft Departed Runway After Landing in Freezing Fog (N74RQ)

Logan-Cache, United States of AmericaLanding (descent or approach)

On January 19, 2005, a Gulfstream GII (registration N74RQ) operated by CFS Air was involved in an aviation accident near Logan-Cache, United States of America during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The pilot's improper IFR operation by which he failed to comply to the missed approach procedure, and his improper evaluation of the weather resulting in an encounter with fog and his loss of visual contact with the runway during the landing. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A pilot initiated a missed approach during a GPS approach, then circled to set up for a visual approach to runway 17. The aircraft entered fog before touchdown, drifted left, and struck a snow berm, causing it to depart the runway.

Approach and Missed Approach Procedure According to the captain, the crew flew a GPS approach to runway 35. When the runway and surrounding environment were not visible, they initiated a missed approach. During the climb, the crew reported seeing the first 4,000 to 5,000 feet of the approach end of runway 17. The captain stated that they elected to circle to the northwest to position the aircraft for a visual approach to runway 17. ## Landing and Runway Departure The captain described the approach as slightly high, resulting in a flare higher than normal. The aircraft entered a fog layer just before touchdown. During the landing flare, the captain said the airplane drifted to the left and settled onto the runway left of the centerline. Shortly afterward, the left main gear struck a snow berm. The aircraft then turned sharply to the left and left the runway. Damage included separation of the nose gear, a crushed radome, and a broken-open cockpit pressure bulkhead. ## Weather Conditions The routine aviation weather report (METAR) at LGU reported calm winds, visibility of 1/4 statute mile in freezing fog, and a vertical visibility of 100 feet above ground level. The temperature and dewpoint were both minus 7 degrees Celsius, and the altimeter setting was 30.45 inches.

Probable cause

The pilot's improper IFR operation by which he failed to comply to the missed approach procedure, and his improper evaluation of the weather resulting in an encounter with fog and his loss of visual contact with the runway during the landing.
