Logan-Cache Airport
Aircraft Accident/Incident Report

Logan, Utah 84335
Wednesday, April 19, 2006 12:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The flight instructor said that he and his son were flying back to their home in Oklahoma in his new airplane. He said that he was giving instruction to his son for a tail-wheel endorsement. He said that everything appeared normal during the landing. The flight instructor said that as the airplane slowed down he noticed some drifting left and right, and then the airplane suddenly ground looped to the right. The left main landing collapsed under the fuselage bending a longeron, and bending and wrinkling the left wing tip.

NTSB Probable Cause Narrative

The pilot receiving instruction failed to maintain airplane directional control during the landing roll, and the flight instructor's inadequate supervision. An inadvertent ground loop was a factor.
