## Discrepancy

DURING CRUISE FLIGHT AT 120 KTS, THE LT SLIDING CABIN DOOR CAME OPEN, SLID ALL THE WAY TO THE STOP AT A HIGH RATE OF SPEED AND POPPED OUT OF THE CENTER GUIDE RAIL.  THE MECHANICS FOUND A BOLT VERY LOOSE (3 OR 4 TURNS LOOSE) IN THE LATCHING MECHANISM  FRICTION SYS, WHICH ALLOWED THE DOOR HANDLE TO VIBRATE OPEN.  THE CENTER GUIDE ARM ABOVE WAS BENT, THE CENTER GUIDE RAIL P/N B520M0037801 WAS BENT OPEN WHERE THE GUIDE POPPED OUT AND THE BACKSTOP P/N B520M4025102 WAS CRACKED.  THE DAMAGED PARTS  WERE REPLACED, THE LOOSE BOLT WAS REMOVED, CLEANED AND REINSTALLED TO PROPER TORQUE WITH THREAD LOCKING FLUID.  NO FURTHER PROBLEMS HAVE OCCURED.
