Aircraft Accident/Incident Report

Falls City, Nebraska 68355
Thursday, July 23, 1998 8:30 CDT

NTSB Narrative Summary Released at Completion of Accident

During the tailwheel airplane's landing roll, its left landing gear leg fractured and separated where the entrance step bolt hole goes through the leg. The airplane ground looped to the left. During the ground loop event the pilot's seat belt mounting bracket separated and the pilot was ejected through the left door. The seat belt mount was made from aluminum rather than the steel the manufacturer said it should have been made from. Fracture surfaces on the separated gear leg show a grainy surface texture. All 4 edges had shear lips on them. There was a series of small arrowhead shapes originating from the gear's leading edge and progressing aft to a point about midway between the bolt hole and leading edge.

NTSB Probable Cause Narrative

the main landing gear leg fracturing and separating from the portion mounted to the fuselage for undetermined reasons.
