Aircraft Accident/Incident Report

Lawrenceville, Georgia 30245
Thursday, April 10, 1997 9:18 EDT

NTSB Narrative Summary Released at Completion of Accident

The student pilot stated that the tower advised him on downwind that another pilot had encountered a wind shear on landing earlier that day. The student pilot completed a touch-and-go landing without incident. He remained in closed traffic for another touch-and-go landing. As he started his round out the airplane encountered gusty wind conditions. The airplane ballooned up and started to settle, when a second gust was encountered and the left wing was pitched downward. The airplane was blown off the left side of the runway while airborne. He attempted a go-around and was reaching for the flaps when he encountered a third gust. The airplane pitched down and the nosewheel collided with the ground. He lost directional control of the airplane, it veered further to the left, and nosed over inverted.

NTSB Probable Cause Narrative

The student pilot's failure to maintain directional control during a crosswind landing. The winds were a factor.
