Primary finding
Probable cause
The failure of the landing gear due to undetected corrosion.
Investigator assessment
Analysis narrative
The commercial pilot had just landed on a 2,630-foot-long by 30-foot-wide asphalt runway with a direct tailwind at 5 knots. The tailwheel was down and the airplane had slowed to a taxi speed when the right landing gear separated from the right landing gear leg, then both wingtips struck the ground causing substantial damage to both wings, and the fuselage. The pilot reported that he thinks the axle failed because of hidden corrosion inside the landing gear tubing that was not detectable during a normal preflight inspection.
