What was found
DURING THE LANDING ROLL-OUT THE LEFT MAIN GEAR COLLAPSED. THE INSPECTION OF THE LANDING GEAR REVEALED THAT THE MAIN GEAR TUBE SEPARATED FROM THE FORK AT THE MOUNT. FURTHER INSPECTION INDICATED THAT THE TUBE HAD CRACKED AT THE MOUNT AND EVENTUALLY SHEARED OFF CAUSING SEPARATION FROM THE WHEEL YOKE. A MAGNIFIED VISUAL INSPECTION SHOWS SIGNIFICANT WEAR AROUND THE TUBE MOUNT BARREL. THIS IS AN INDICATION THAT THE TUBE HAD BEEN WORKING LOOSE IN THE BORE. THIS ISSUE WOULD BE DIFFICULT TO DETECT WITHOUT REMOVING THE TUBE FROM THE YOKE AND CHECKING FOR CRACKS.
