## Abstract

We are adopting a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This AD requires repetitive replacement of the internal electrical feed-through connectors of the boost pumps of the main fuel tank. This AD results from a report of cracking in the epoxy potting compound on the internal feed-through connector of the fuel boost pump in the area of the soldered wire connector lugs. We are issuing this AD to prevent a hazardous electrical path from the dry side to the wet side of the fuel boost pump through a cracked feed- through connector, or between pins or a pin and the shell on one side of the feed-through connector, which could create an ignition source on the wet side of the fuel boost pump or cause a fire in the fuel pump enclosure and lead to subsequent explosion of the fuel tank.
