Airworthiness Directive 2016-11-06
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are superseding Airworthiness Directive (AD) 2005-18-18 for certain The Boeing Company Model 757 airplanes. AD 2005-18-18 required inspections of certain wire bundles in the left and right engine-to- wing aft fairings for discrepancies; installation of back-to-back p- clamps between the wire and hydraulic supply tube at the aft end of the right-hand strut only; and associated re-routing of the wire bundles, if necessary. This new AD also requires an installation of spiral cable wrap on fuel shutoff valve (FSV) wires at the aft end of the strut, for both left and right engines, and related investigative and corrective actions. This AD was prompted by a determination that the service information referenced in AD 2005-18-18 did not adequately address FSV wires at the aft end of the struts. We are issuing this AD to prevent chafing between the wire bundle and the structure of the aft fairing, which could result in electrical arcing and subsequent ignition of flammable vapors and a possible uncontrollable fire.
Which aircraft AD 2016-11-06 applies to
Applies only to 757 airplanes equipped with Rolls-Royce engines, as identified in Boeing Alert Service Bulletins 757-28A0073 and 757-28A0074, both Revision 2, both dated June 4, 2009.
Whether AD 2016-11-06 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.
