## Discrepancy

DURING ROUTINE INSPECTION OF ACFT LANDING GEAR RETRACTION SYS, THE LANDING GEAR ACTUATOR WAS EXCESSIVELY NOISEY WHEN THE LANDING GEAR WAS RETRACTED AND EXTENDED.AFTER FURTHER EXAMINATION OF THE ACTUATOR IT WAS DISCOVERED THAT THE (INTERNAL) BOLTS THAT SECURE THE RETAINER PLATE FOR THE "NO BACK SPRING" WERE MISSING.  A NEW ACTUATOR WAS INSTALLED AND THE PROBLEM WAS CORRECTED.
