## Discrepancy

DURING A 50 HR INSP, IT WAS DISCOVERED THAT THE STANDPIPE IN THE FUEL STRAINER TOP ASSY, PN:0756005-2, (PARTS CATALOGUE FIG 183, ITEM 3) HAD A RING OF CORROSION AROUND THE PIPE WHERE IT WAS IN CONTACT WITH THE STRAINER SCREEN.  THE CORROSION COMPLETELY PENETRATED THE PIPE IN PLACES AND IT APPEARED THE CONDITION COULD ALLOW UNFILTERED FUEL TO ENTER THE STRAINER SCREEN.  IT IS SUSPECTED THAT THE CORROSION IS OF THE DISSIMILAR METAL METAL TYPE.  A CHECK OF 2 OTHER ACFT REVEALLED THE SAME CONDITION.  ALL SUBJECT AIRCRAFT, ALL WITH IN EXCESS OF 10,000 FLIGHT HRS EA.
