Aircraft Accident/Incident Report

Hudson, Colorado 80642
Sunday, December 28, 2003 12:00 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot said he was landing on runway 33 into a left 30-degree crosswind (later he said it was a 70-degree crosswind). "An apparent gust" of approximately 40 mph "caused the airplane to ground loop to the left side of the runway. The airplane departed the runway, "it appears the right wheel dug into the sandy ground," and the airplane nosed over. According to the Wind Component Chart, under the conditions described by the pilot, a 30-degree, 40 mph crosswind would produce a crosswind component of 20 mph. A 70-degree, 40 mph crosswind would produce a crosswind component of 38 mph. According to a spokesperson for the airplane manufacturer, the maximum crosswind component for the airplane is 15 mph.

NTSB Probable Cause Narrative

the pilot's failure to maintain directional control due to an excessive crosswind component, resulting in an uncontrolled groundloop/swerve. Contributing factors were the crosswind gust and the soft, sandy terrain.
