Airworthiness Directive 2000-11-08
one-timeAirworthiness Directives; Boeing Model 747 and 767 Series Airplanes Powered by General Electric Model CF6-80C2 Series Engines
What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 747 and 767 series airplanes, that currently requires revising the FAA-approved Airplane Flight Manual (AFM) to prohibit the use of certain fuels; and either replacing an existing placard with a new placard, or replacing all dribble flow fuel nozzles (DFFN) with standard fuel nozzles, which terminates the requirements for the new placard and AFM revision. This amendment continues these requirements and adds identical requirements applicable to airplanes on which standard fuel nozzles are not installed. This amendment is prompted by a report of an engine flameout due to use of JP-4 or Jet B fuel during certification testing on an engine with DFFN's installed. The actions specified by this AD are intended to prevent such engine flameouts and consequent engine shutdown.
Which aircraft AD 2000-11-08 applies to
Applies to Model 747 series and Model 767 series airplanes on which a dribble flow fuel nozzle (DFFN) having General Electric P/N 9331M72P33, 9331M72P34, or 9331M72P41 is installed on any engine in a specific operator's fleet, per Boeing Alert Service Bulletin 747-11A2052 (or Rev 1) for Model 747 series airplanes, and Boeing Alert Service Bulletin 767-11A0031 (or Rev 1) for Model 767 series airplanes. Restatement of requirements of AD 98-08-23; requires AFM revision and either placarding or DFFN replacement to prohibit/prevent use of JP-4 and Jet B fuel.
Whether AD 2000-11-08 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.
