## Discrepancy

DURING INSPECTION ON JUNE 26, 2008 IT WAS NOTED THAT THERE WAS A CRACK THAT WENT AROUND THE CIRCUMFERENCE OF THE NR 7 EXHAUST FLANGE.  A NEW MANIFOLD ASSY WAS ORDERED AND INSTALLED.  WHILE REMOVING THE CRACKED ONE, IT WAS DISCOVERED THAT THERE HAD BEEN COMPLETE SEPARATION.  THIS EXHAUST MANIFOLD IS A PMA PART FOR THE ENGINES, AND WAS INSTALLED NEW AT OVERHAUL 1505 HOURS PRIOR.  IT WAS NOTED THAT A NEW WELDING TECHNIQUE HS BEEN USED RECENTLY IN THE FLANGE AREA.  (K)
