Airworthiness Directives; Boeing Model 777-200, -200LR, -300, and -300ER Series Airplanes Approved for Extended-Range Twin-Engine Operational Performance Standards (ETOPS)

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires a one-time inspection to determine the part number of the cargo compartment fire suppression filter/regulator. This AD also requires, for certain airplanes, a revision of the "Maximum Diversion Time in Minutes" for ETOPS operation specified in the Operations Specifications. For certain airplanes, this AD also provides for optional replacement of the cargo compartment fire suppression filter/ regulator, which would allow revision of the "Maximum Diversion Time in Minutes" for ETOPS operation specified in the Operations Specifications to restore the airplane's full ETOPS capability. This AD results from a report that the filter/regulator installed in the cargo fire suppression system did not meter the Halon for the certified duration during ETOPS flight tests. We are issuing this AD to prevent ETOPS operation with insufficient cargo fire suppression capability, which could result in an uncontained fire in the cargo compartment.

Applies only to 777-200/-200LR/-300/-300ER airplanes approved for extended-range twin-engine operations (ETOPS).

Whether AD 2008-14-11 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 2008-14-11 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.
