What was found
ON 9/11/08 DURING AN INSP, IT WAS FOUND THAT THE EXHAUST FLANGE WHERE THE MANIFOLD IS CLAMPED TO THE WASTE GATE HOUSING, THERE WAS A CRACK IN THE FLANGE RADIUS THAT RAN APPROXIMATELY .3333 OF THE WAY AROUND THE PIPE. THE MANIFOLD ASSY WAS REPLACED WITH A NEW ASSY. IT IS HIGHLY RECOMMENDED TO PAY CLOSE ATTENTION TO THE FLANGES AND WELDS ON THESE PMA ASSEMBLIES, AS FAILURE OF THE EXHAUST PIPES COULD CAUSE CONSIDERABLE DAMAGE TO THE AIRCRAFT. IT MUST BE NOTED THAT THE MFG WELD PROCESS IN THIS AREA HAS RECENTLY CHANGED. (K)
