Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of unreliable performance of the fuel scavenge system. This AD requires changing the main fuel tank water scavenge system, center fuel tank fuel scavenge system, and certain electrical panels; doing related investigative actions; doing corrective actions if necessary; and, for certain airplanes, changing the fuel scavenge system to give redundant control of the center override/jettison fuel pumps and main jettison fuel pumps. We are issuing this AD to prevent fuel exhaustion and subsequent power loss of all engines due to loss of capability to scavenge fuel in the center fuel tank.

Which aircraft AD 2016-11-03 applies to

As identified in Boeing Special Attention Service Bulletin 777-28-0078, Revision 1, dated April 27, 2015.

Whether AD 2016-11-03 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2016-11-03 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
