Aircraft Accident/Incident Report

Concord, California 94520
Friday, May 18, 2001 15:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The airplane ground looped during the landing roll. The pilot noted prior to landing that there was a 90-degree crosswind at 10 knots. During the landing roll the airplane veered to the right. When the pilot added full left rudder and brakes he overcorrected the airplane and it veered to the left. He was not able to return the airplane back to runway heading. The airplane continued in a left circle and ground looped. No mechanical anomalies were noted with the airplane by the pilot.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for wind conditions, resulting in a loss of directional control and the inadvertent ground loop.
