IT WAS NOTED UPPON DISSASSEMBLY OF THE ELEVATOR FOR REPAIR THAT WASHER WAS MISSING FROM UNDER NUT OF TORQUE TUBE P/N 50-610000-234 ATTACH BOLT P/N NAS1103-5. ONCE DISSASSEMBLY OF THE TORQUE TUBE, RIB AND BRACKET WAS CARRIED OUT, IT WAS NOTED THAT THE BRACKET P/N 50-610000-90 HAD CRACKS THAT WERE NOT VISSABLE UNTIL THE TORQUE TUBE WAS REMOVED.
