## Discrepancy

DURING A SCHEDULED INSPECTION,  FOUND WEB ASSY CRACKED WHERE THE CABIN DOOR HANDLE ASSY ATTACHES TO IT WITH NUT PLATES.  AFTER REVIEW OF IPC, DISCOVERED STIFFENER SHOULD HAVE BEEN INSTALLED ON THIS ACFT DURING PRODUCTION.  INSTALLATION OF STIFFENER AND OTHER MODIFICATIONS ARE PART OF SB560XL-52-14 FOR EARLIER SN ACFT.
