(CAN) UPON INSPECTION OF THE REVERSING LEVER GUIDE PIN BRACKET FOR WEAR DURING AN ENGINE BUILD UP IT WAS NOTICED THAT THE BRACKET PLATE THAT THE GUIDE PIN IS WELDED TO WAS CRACKED. THE CRACK WAS ADJACENT TO THE PIN WELD AND ON THE FORWARD SIDE OF THE PLATE. TOTAL FAILURE OF THE PLATE WOULD CAUSE THE PIN TO DISLODGE ALLOWING THE BETA ARM TO ROTATE OUT OF THE PROPELLER REVERSING ARM SLIP RING.
