## Discrepancy

THE UH-72 HAS HAD MULTIPLE REPORTS OF MISSING DOOR HANDLES AFTER RETURN FROM MISSION.  THE ROOT CAUSE OF THE PROBLEM IS THE ATTACHING SCREW BECOMES LOOSE AFTER A FEW HOURS IN SERVICE WHICH THE DOOR HANDLE WILL FALL OFF.  THIS INTRODUCES FOD THAT HAS A POSSIBILITY TO GET IN THE ROTOR SYSTEM.  THIS ATTACHING HARDWARE IS INSERTED INTO A THREADED HOLE THAT HAS NO LOCKING DEVICE, LOCTITE HAS BEEN USED TO HELP BUT HASN'T BEEN THAT SUCCESSFUL.
