## Discrepancy

DURING A 100-HOUR INSPECTION, THE RT MAIN TIRE WAS BEING ROTATED.  DURING INSPECTION OF MAIN WHEEL CENTER HUB, CRACKS WERE DISCOVERED AT EACH BOLT HOLE (6) ON THE OUTBOARD SIDE OF WHEEL.  ALSO, ON THE INBOARD SIDE 3 OF THE 6 HOLES SHOWED CRACKS TOO.  THIS AIRCRAFT IS USED FOR TRAINING PURPOSES.  POSSIBLE CAUSE, REPEATED HARD LANDINGS.
