Airworthiness Directive 2017-11-14
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are superseding Airworthiness Directive (AD) 2011-26-03, which applied to certain The Boeing Company Model 777-200, -200LR, - 300, and -300ER series airplanes. AD 2011-26-03 required installing Teflon sleeving under the clamps of certain wire bundles routed along the fuel tank boundary structure, and cap sealing certain penetrating fasteners of the main and center fuel tanks. This AD requires certain inspections for certain airplanes, corrective actions if necessary, and installation of Teflon sleeves under certain wire bundle clamps. This AD was prompted by a report indicating that additional airplanes are affected by the identified unsafe condition. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-11-14 applies to
Applicability varies by model and service bulletin: 777-200/-200LR/-300/-300ER/777F per Boeing SB 777-57A0050 Rev 4, dated September 28, 2015; 777-200/-300 per Boeing ASB 777-57A0051, dated May 15, 2006; 777-200/-300/-300ER per Boeing ASB 777-57A0057 Rev 1, dated August 2, 2007; 777-200/-200LR/-300/-300ER per Boeing ASB 777-57A0059, dated October 30, 2008.
Whether AD 2017-11-14 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.
