What was found
(CAN) DURING A SCHEDULED INSTALLATION OF A NOSE GEAR GRAVEL DEFLECTOR, THE R/H NLG WHEEL OUTER BEARING WAS DISCOVERED SEIZED. THE WHEEL WAS STILL ABLE TO ROTATE ON ITS AXIS, BUT DIFFICULT TO REMOVE FROM THE AXLE. AFTER REMOVAL OF THE WHEEL, SEVERE AXLE DAMAGE WAS NOTED. IT IS SUSPECTED THAT THE INNER RACE OF THE BEARING WAS JAMMED, CAUSING IT TO RUB ON THE AXLE. NOSE LANDING GEAR SHOCK STRUT AND BOTH NLG WHEELS WERE REPLACED. (TC# 20190506010)
