Aircraft Accident/Incident Report
Conway, Arkansas 72032
Wednesday, July 25, 2012 9:30 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that after completing an uneventful straight-in approach, the right main landing gear collapsed upon touchdown. The airplane subsequently swerved to the right, departing off the right side of the runway. A laboratory examination revealed a longitudinal crack along the leading edge of the right landing gear leg and a transverse fracture near the point where the leg intersected the fuselage. Observed fiber pullout and parallel transverse cracks in the paint adjacent to the fracture were consistent with a bending load, with the lower surface in tension and the upper surface in compression. No preexisting damage or manufacturing anomalies were noted with the right main landing gear that would have reduced its design strength. The lack of any observed material defects or preexisting damage suggests that the right main landing gear fractured when it experienced a bending load that exceeded its design requirements, likely during the accident sequence.
NTSB Probable Cause Narrative
The pilot's improper landing flare, which resulted in a hard landing and overstress failure of the right main landing gear.
