SUPPLEMENTAL INFORMATION

Airworthiness Directive (AD) 2000-15-17, amendment 3911849, applicable to certain McDonnell Douglas Model DC9 81 (MD81), DC982 (MD82), DC983 (MD83), and DC987 (MD87);
Model MD88 airplanes; and Model MD9030 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 MD88 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 MD8053286, 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 MD8053286, dated September 3, 1999, affects McDonnell Douglas Model DC981 (MD81), DC982 (MD 82), DC983 (MD83), and DC987 (MD87) series airplanes, and Model MD88 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. Sec. 39.13 [Corrected]

On page 48371, in the first column, paragraph (c) of AD 20001517 is corrected to read as follows:
20001517 McDonnell Douglas: Amendment 3911849. Docket 99NM227 AD.
