INSTALLED THE STAIRS AND OPERATIONS CHECKED THE DOOR. THE DOOR HANDLE OPERATED SMOOTHER THAN BEFORE. CHECKED THE FITTING OF THE ECCENTRIC AND NO DEFECTS WERE NOTED. SINCE THE PINS WERE CATCHING ON THE LATCH PLATES WE REMOVED ONE LATCHING PLATE AT A TIME AND FOUND THE FORWARD UPPER LATCH TO BE OUT OF ADJUSTMENT. ADJUSTED THE UPPER FORWARD LATCH AND OPERATIONS CHECKED THE DOOR. ALL CHECKS GOOD AT THIS TIME. WORK DONE IN REF TO CE-560XL AMM 52-10-00.
