## Discrepancy

(CAN) DURING THE UNSCHEDULED REMOVAL OF NR 2 PROP DUE TO OIL LEAKING FROM THE PROP SHAFT, IT WAS NOTICED THAT THE PROP SHAFT OIL RUNNER (PART OF THE POWER SECTION) WOULD ROTATE WITHOUT THE PROP SHAFT MOVING. INFORMED US THAT THIS IS AN INDICATION THAT BEARING RETAINING NUT ASSY (NUT P/N 3022710) MAY HAVE LOOSENED UP. THE POWER SECTION WAS REMOVED AND SENT FOR REPAIR.
