A NEW PART WAS INSTALLED IAW THE REQUIREMENTS OF AD2004-01-14 AN INSPECTION DUE AT 110 HOUR INTERVAL. THIS IS A FAIRLY COMMON DEFECT FOR THIS PART. SUGGEST THE NEW IMPROVED PN ASSY BE MADE IN QUANTITIES SO ALL AC MAY BE UPDATED TO THE LATEST NON AD EFFECTED PN. THIS IS A MFG SUPPLY ISSUE THAT THE OEM REFUSES TO ADDRESS. (K)
