SUMMARY: This document corrects a typographical error that appeared in 
airworthiness directive (AD) 2000-15-17 that was published in the 
Federal Register on August 8, 2000 (65 FR 48368). The typographical 
error resulted in the omission of an airplane model from paragraph (c) 
of the AD. This AD is applicable to certain McDonnell Douglas Model DC-
9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87); 
Model MD-88 airplanes; and Model MD-90-30 series airplanes. This AD 
requires installation of a pipe support and clamps on the hydraulic 
lines in the aft fuselage; replacement of the hydraulic pipe assembly 
in the aft fuselage with a new pipe assembly; and installation of drain 
tube assemblies and diverter assemblies in the area of the auxiliary 
power unit inlet; as applicable.

DATES: Effective September 12, 2000.

FOR FURTHER INFORMATION CONTACT: Albert Lam, Aerospace Engineer, 
Systems and Equipment Branch, ANM-130L, FAA, Los Angeles Aircraft 
Certification Office, 3960 Paramount Boulevard, Lakewood, California

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 2000-15-17, 
amendment 39-11849, applicable to certain McDonnell Douglas Model DC-9-
81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87); 
Model MD-88 airplanes; and Model MD-90-30 series airplanes, was 
published in the Federal Register on August 8, 2000 (65 FR 48368). That 
AD requires installation of a pipe support and clamps on the hydraulic 
lines in the aft fuselage; replacement of the hydraulic pipe assembly 
in the aft fuselage with a new pipe assembly; and installation of drain 
tube assemblies and diverter assemblies in the area of the auxiliary 
power unit (APU) inlet; as applicable.
    As published, that AD contained a typographical error in paragraph 
(c) of the AD, which resulted in the omission of Model MD-88 airplanes 
from its applicability. It was the FAA's intent that the applicability 
of paragraph (c) of the AD be parallel to that recommended by the 
manufacturer in its referenced service bulletin (i.e., McDonnell 
Douglas Service Bulletin MD80-53-286, dated September 3, 1999). As was 
indicated under the heading ``Explanation of Relevant Service 
Information'' in the preamble of the notice of proposed rulemaking 
(NPRM), McDonnell Douglas Service Bulletin MD80-53-286, dated September 
3, 1999, affects McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-
82), DC-9-83 (MD-83), and DC-9-87 (MD-87) series airplanes, and Model 
MD-88 airplanes.
    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 September 12, 2000.
