Airworthiness Directives; The Boeing Company Airplanes

Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model MD-11 and MD-11F airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require 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 proposing this AD to address the unsafe condition on these products.
