Aircraft involved
Probable cause & findings
The pilot' failure to identify the plowed runway width in dusk and flat light conditions, which resulted in a touchdown left of the runway center, an impact with a snow berm, and a ground loop.
Factual narrative
The pilot reported that during the approach he was informed by a person on the ground, who was not associated with airport operations, that there was about 3 inches of compacted snow on the runway. Before attempting to land, he completed a low pass over the runway to observe the runway conditions, but reported that it was dusk and he was observing flat light conditions. The pilot reported that the touchdown was normal, but about 50 to 75 feet into the landing roll the airplane pulled to the left. He attempted to correct with right rudder, but was unable to stop the airplane from ground looping to the left into a snow berm. After the accident, the pilot observed that he "landed left of center" and the left main landing gear caught a one foot snow berm. The right wing and right elevator were substantially damaged. According to the Federal Aviation Administration Airport Facility Directory, the destination had "intermittent" snow removal and the airport manager could be called for current conditions. The runway used was not equipped with runway lights. The pilot reported there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
