Start Preamble

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.

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.
