## Discrepancy

AFTER INSPECTION OF PAWL RETAINING RIVET, IT WAS FOUND TO BE BEYOND ITS ACCEPTABLE LIMITS LISTED IN 3.3.4 OF THE SLICK INDUSTRIES MAINTENANCE AND OVERHAUL MANUAL P/N L-1363C. A PREMATURE WEAR OF THE PAWL RETAINING RIVETS WAS NOTICED UNDER NORMAL WEAR CONDITIONS. RECOMMEND TO INSPECT THE METOLOGY OF THE RIVETS FOR CORRECT TEMPER, WHICH IF NOT FOUND, THE PAWLS COULD COME APART AND POSSIBLY CAUSE LOSS OF ENGINE POWER.
