## Discrepancy

(CAN) BULKHEAD WAS INSTALLED IAW CESSNA SK172-156A INSTRUCTIONS. BULKHEAD HAS CRACKS CURVING AROUND BOLT HOLES ABOUT HALF INCH AWAY FROM THE HOLE EDGE AT THE INNER BEND RADIUS.  NOTE: THIS IS THE FOURTH OR FIFTH IDENTICALLY CRACKED BULK HEAD FOUND ON AS MANY OTHER 172 A/C IN THE PAST THREE OR SO MONTHS AT OUR FACILITY. CESSNA IS GIVING US WARRANTY FOR THE PARTS BUT NO CORRECTIVE ACTION HAS COME FORWARD AS YET. (TC# 20061031002)
