## Discrepancy

UPON LANDING IN BCT, CREW ATTEMPTED TO EXIT AIRCRAFT THROUGH MAIN CABIN DOOR, THEY WERE UNABLE TO ACTUATE THE TRIGGER ON THE DOOR HANDLE, AND THUS UNABLE TO MOVE THE DOOR HANDLE TO THE OPEN POSITION. LINE SERVICE OPENED DOOR FROM THE OUTSIDE, ALLOWING CREW TO DISEMBARK. UPON INSPECTION, FOUND TRIGGER STOP (UPPER MOST PORTION OF TRIGGER P/N 5519055-14) BROKE OFF FROM THE REST OF THE TRIGGER AND WAS JAMMED BEHIND TRIGGER, PREVENTING TRIGGER FROM BEING ABLE TO ACTUATE. REPLACED TRIGGER P/N 5519055-14 WITH NEW, OPS CHECK WAS GOOD.
