## Discrepancy

DURING INSPECTION, FOUND LT MLG UPLOCK ASSY LOOSE IN AIRCRAFT STRUCTURE.  ALL 4 BOLTS (AN4-7A) WERE LOOSE.  NO SAFETY DEVICE OTHER THAN SELF-LOCKING NUTPLATE (MS21069L4).  TORQUED BOLTS AND APPLIED LOCTITE 271 THREAD LOCKER.  FOUND RT UPLOCK ASSY SECURE, BUT BOLTS ALSO UNDER TORQUED.
