## Discrepancy

DURING INSPECTION,  A CRACK WAS FOUND ON THE LOWER LEFT PORTION OF THE CABIN DOOR FRAME AT BS 243.38.  THE CRACK ORIGINATES FROM A BEND RELIEF CUTOUT IN A HEAVILY FORMED SECTION OF THE FRAME.  THIS IS THE THIRD AIRCRAFT WE FOUND THIS CRACK PRESENT, SAME MAKE AND MODEL.  THE REGION OF THE FRAME HAS TO BE DISASSEMBLED AND INSPECTED FOR OTHER SIGNS OF DAMAGE OR DISTRESS.  AN ENGINEERED DOUBLER HAS TO BE INSTALLED WITH STRUCTURAL ADHESIVE AND RIVETS.
