Read the full NTSB narrative

THE RIGHT MAIN OUTBOARD WHEEL DEPARTED THE AIRCRAFT DURING THE TAKEOFF ROLL. THE TOWER INFORMED THE CREW WHO REPORTED THAT ALL COCKPIT INDICATIONS WERE NORMAL. THE AIRPLANE LANDED AT THE DESTINATION WITHOUT FURTHER INCIDENT. THE OUTBOARD WHEEL BEARING HAD FAILED IN A MANNER THAT THE BEARING CAGE LOST ITS ABILITY TO RETAIN THE ROLLERS. BOTH BOLTS USED TO LOCK THE RETAINER NUT TO THE AXLE WERE IN PLACE. THE WHEEL SPACER WAS SEIZED TO THE INNER RACE OF THE OUTER BEARING AND A DISTINCT RIDGE WAS SEEN ON THE DAMAGED SPACER. NTSB METALLURGICAL EXAMINATION REVEALED THE SPACER WAS ROTATING ON THE AXLE; HOWEVER, THE ORIENTATION OF THE SPACER COULD NOT BE DETERMINED. THE OUTBOARD WHEEL BEARING DISCLOSED EVIDENCE OF OVERHEATING.
