Aircraft Accident/Incident Report
Seattle, Washington 98108
Thursday, March 10, 2011 18:41 PST
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that following two attempts to land in crosswind conditions, he was cleared to land and was instructed by the air traffic control tower controller to follow another airplane on final approach. For spacing considerations, the controller instructed the pilot to conduct "S" turns behind the traffic landing ahead of him. As the airplane descended to an altitude of about 200 feet above ground level, the controller instructed the pilot to go around and maintain altitude. The pilot executed a go-around procedure, which included retracting the landing gear and reducing the flap setting to one-half flaps. Shortly after, the pilot was issued a clearance to land. The pilot proceeded with the landing clearance and subsequently landed with the gear in the retracted position, which resulted in structural damage to the airframe. Postaccident examination of the airplane revealed no mechanical anomalies or failures with the landing gear or landing gear warning system.
NTSB Probable Cause Narrative
The pilot's failure to extend the landing gear, which resulted in a gear-up landing.
