Aircraft Accident/Incident Report
Wellington, Colorado 80549
Saturday, April 2, 2011 9:47 MDT
NTSB Narrative Summary Released at Completion of Accident
On final approach to the runway, the pilot had difficulty maintaining centerline on the 15-foot-wide runway. The pilot requested assistance from the certified flight instructor (CFI) who directed a go-around. After the pilot began the go-around procedures, the CFI took control of the airplane and reduced the flap setting. The airplane was flown in ground effect as the airplane drifted to the left of the runway. The airplane was not at a safe flying airspeed to maneuver away from a gazebo and windsock. The airplane's left wing collided with the gazebo and the right wing collided with the windsock. The CFI performed a forced landing and the airplane skidded to a stop. The airframe sustained substantial crushing damage to both wings and the forward fuselage, including the firewall. A postaccident examination of the engine and airframe did not reveal any anomalies that would have prevented normal operation.
NTSB Probable Cause Narrative
The certified flight instructor's failure to maintain directional control during the go-around.
