Airworthiness Directive 2017-28379
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model MD-11 and MD-11F airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires a one-time inspection of the wire assemblies of the tail fuel tank transfer pumps to determine if metallic transitions are installed at the wire harness breakouts, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-28379 applies to
Applicability as identified in Boeing Alert Service Bulletin MD11-28A150, dated October 6, 2016.
Whether AD 2017-28379 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.
