## Discrepancy

UPON C/W AD 76-13-07, REPLACEMENT OF FORK BOLTS, PLAY WAS NOTICED AT ADJUSTING SCREW/DOWNLOCK SWITCH LOCK LINK.  UPON FURTHER INSPECTION, THREADS WERE SHOWN TO BE WORN AND PART WAS ALLOWED ABOUT 5 THOUSANDS OF AN INCH IN PLAY.  THIS IS THE SECOND REPORT FILED ON THIS PART NUMBER AND SECOND RECOMMENDATION OF MANDATORY AD OF 2,500-HOUR REPLACEMENT.  THIS IS THE ONLY DOWNLOCK LOAD ON THE GEAR SIDE BRACE AND UPON FAILIURE, IS GUARANTEED GEAR FAILURE/COLLAPSE.  (X)
