Airworthiness Directives; Boeing Model 747 and 767 Series 
Airplanes Powered by General Electric Model CF6-80C2 Series Engines; 
Correction

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: This document corrects a typographical error that appeared in 
airworthiness directive (AD) 2000-11-08, amendment 39-11756, that was 
published in the Federal Register on June 1, 2000 (65 FR 34935). The 
typographical error resulted in a reference to an incorrect fuel 
specification. That AD is applicable to certain Boeing Model 747 and 
767 series airplanes. That AD supersedes an earlier airworthiness 
directive to require 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. That AD also 
includes identical requirements applicable to airplanes on which 
standard fuel nozzles are not installed.

DATES: Effective July 6, 2000.

FOR FURTHER INFORMATION CONTACT: Ed Hormel, Aerospace Engineer, 
Propulsion Branch, ANM-140S, FAA, Seattle Aircraft Certification 
Office, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone 
(425) 227-2681; fax (425) 227-1181.

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 2000-11-08, 
amendment 39-11756, applicable to certain Boeing Model 747 and 767 
series airplanes, was published in the Federal Register on June 1, 2000 
(65 FR 34935). That AD supersedes AD 98-08-23, amendment 39-10472 (63 
FR 18817, April 16, 1998) to require 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. That 
AD also includes identical requirements applicable to airplanes on 
which standard fuel nozzles are not installed.
    As published, AD 2000-11-08 contains an erroneous fuel 
specification in paragraphs (a)(1)(i) and (c)(1) of that AD. Those 
paragraphs incorrectly reference MIL-T-83113, which is a specification 
that does not exist. The correct reference is MIL-T-83133.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.

    Accordingly, in FR Doc. 00-13447 published June 1, 2000 (65 FR 
34935), make the following corrections:
    The effective date of this AD remains July 6, 2000.
