Airworthiness Directives; Boeing Model 767 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects two typographical errors that appeared 
in airworthiness directive (AD) 98-07-26, which was published in the 
Federal Register on April 6, 1998 (63 FR 16681). The typographical 
errors resulted in a reference to an incorrect part number and 
incorrect section of the referenced service information. This AD is 
applicable to certain Boeing Model 767 series airplanes. This AD 
requires detailed visual inspection(s) for damage or chafing of certain 
electrical wire bundles and for clearance between the wire bundles and 
adjacent forward galley air chiller; and follow-on corrective actions.

DATES: Effective April 21, 1998.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of April 21, 1998 (63 FR 16681, April 6, 1998).

Engineer, Systems and Equipment Branch, ANM-130S, FAA, Transport 
Airplane Directorate, Seattle Aircraft Certification Office, 1601 Lind 
Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-1279;

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 98-07-26, 
amendment 39-10448, applicable to certain Boeing Model 767 series 
airplanes, was published in the Federal Register on April 6, 1998 (63 
FR 16681). That AD requires detailed visual inspection(s) for damage or 
chafing of certain electrical wire bundles and for clearance between 
the wire bundles and adjacent forward galley air chiller; and follow-on 
corrective actions.
    As published, that AD contained two typographical errors in 
paragraphs (a)(1)(ii), (a)(2), (a)(3)(ii), and (a)(4). First, those 
paragraphs identified ``Section 20-00-11'' of the Boeing Standard 
Wiring Practices Manual as the appropriate source of service 
information for accomplishment of the actions. However, the correct 
section should have been identified as ``Section 20-10-11.'' Second, 
those paragraphs identified ``TFX-2X standard wall thickness (sleeve)'' 
as one of the appropriate materials to protect the bundles. However, 
part number (P/N) ``TFX-2X'' was indicated inadvertently in those 
paragraphs instead of the correct P/N ``TFE-2X.'' (In fact, P/N ``TFX-
2X'' does not exist.)
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
    The effective date of this AD remains April 21, 1998.
    In final rule, FR Doc. 98-8705, published on April 6, 1998 (63 FR 
16681), make the following corrections:
