Airworthiness Directive 2009-23-04
recurringAirworthiness Directives; Boeing Model 767 Airplanes
What this AD requires
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.
Which aircraft AD 2009-23-04 applies to
Whether AD 2009-23-04 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
