## Discrepancy

FOUND VERY SLIGHT MOVEMENT IN RT MLG OB PART OF MLG STRUT. UPON FURTHER INVESTIGATION, FOUND THAT P/N 10574X-YR1145 BUSHING WAS NOT INSTALLED IN MLG STRUT. FURTHER INVESTIGATION FOUND THAT THIS AREA HAD NOT BEEN THOROUGHLY INSPECTED SINCE DECEMBER 2004 DURING 6 YEAR INSPECTION OF LANDING GEAR.  INSPECTED MLG ATTACH AREA FOR DAMAGE, NONE FOUND, INSPECTED TRUNNION ATTACH AREA, NO DAMAGE FOUND. INSTALLED NEW BUSHINGS, BOLTS, WASHERS AND NUTS. SUBMITTER SUGGESTS THAT THOROUGH VISUAL INSPECTION OF BUSHING INSTALLATION BE CONDUCTED BEFORE INSTALLING WASHER AND NUT ON BOLT P/N 130909B95.
