## Discrepancy

DURING ANNUAL INSP FOUND COULD ROTATE ONE BLADE AN EXCESSIVE DISTANCE, SENT OUT FOR REPAIR AND IT WAS FOUND THAT THE INSIDE STAINLESS STEEL RETAINER HAD FAILED AND ALLOWED THE BALL BEARINGS TO FALL OUT OF THEIR SEAT, HUB WAS DAMAGED BEYOND REPAIR AND IT WAS CLOSE TO INFLIGHT FAILURE WHICH COULD HAVE CAUSED SEPARATION OF THE BLADE FROM THE HUB.
