## Discrepancy

(CAN) DUE TO PREVIOUS IMPULSE COUPLING FAILURES, WE IMPLEMENTED AN IMPULSE COUPLING INSPECTION EVERY 100 HRS. THIS IMPULSE COUPLING WAS FOUND TO HAVE A LOOSE PAWL RIVET.  SLICK SB1-98 WAS CARRIED OUT AND THE PAWL GAPS WERE FOUND TO BE WITHIN LIMITS, AND THE T-155 RIVET GAUGE SHOWED NO WEAR.  THE IMPULSE CO UPLING WAS REPLACED WITH A NEW ONE.
