What was found
(CAN) DURING A WALKAROUND THE PILOT NOTICED THE BRAKE DISC WAS RUBBING AGAINST THE SIDE OF THE GEAR FORK. AFTER THE WHEEL ASSEMBLY WAS REMOVED A CRACK WAS FOUND ON THE AXLE AT THE INNER MOST BEARING RIDE LOCATION. THE CRACK WAS MORE THAN A THIRD OF THE WAY AROUND THE AXLE. THE CRACK HAD STARTED ON THE BOTTOM AREA OF THE AXLE WHICH IS HARD TO SEE UNLESS A MIRROR IS USED DURING NORMAL INSPECTION.
