Amendment 39-13951; AD 2005-02-06]
RIN 2120-AA64
Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-
11F Airplanes Equipped With Pratt & Whitney PW4000 Series Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain McDonnell Douglas Model MD-11 and MD-11F airplanes equipped
with Pratt & Whitney PW4000 series engines. This AD requires, for each
engine, replacing, with a tube assembly, the existing hose assembly
that connects the oil pressure transmitter to the main oil circuit.
This AD is prompted by a report indicating that, for each engine, the
existing hose assembly does not meet zero-flow fireproof capability
requirements. We are issuing this AD to prevent, if there is an engine
fire, failure of the oil pressure indicator and the low-oil pressure
warning, which could result in an unannounced shutdown of that engine;
and oil leakage, which may feed the engine fire.
DATES: This AD becomes effective March 7, 2005.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of March
7, 2005.
ADDRESSES: For service information identified in this AD, contact
Boeing Commercial Airplanes, Long Beach Division, 3855 Lakewood
Boulevard, Long Beach, California 90846, Attention: Data and Service
Management, Dept. C1-L5A (D800-0024). You can examine this information

Docket: The AD docket contains the proposed AD, comments, and any
final disposition. You can examine the AD docket on the Internet at
http://dms.dot.gov, or in person at the Docket Management Facility
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-

identifier for this docket is 2004-NM-07-AD.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39
with an AD for certain McDonnell Douglas Model MD-11 and MD-11F
airplanes equipped with Pratt & Whitney PW4000 series engines. That
action, published in the Federal Register on October 27, 2004 (69 FR
62629), proposed to require, for each engine, replacing, with a tube
assembly, the existing hose assembly that connects the oil pressure
transmitter to the main oil circuit.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
submitted on the proposed AD. The commenters support the proposed AD.
Conclusion
We have carefully reviewed the available data, including the
comments that have been submitted, and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 76 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this AD.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Replacement of Hose Assemblies
(f) Within 18 months after the effective date of this AD: For
each engine, replace the existing hose assembly, part number (P/N)
113286, that connects the oil pressure transmitter to the main oil
circuit, with tube assembly P/N 221-5318-501. Do the replacement in
accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin MD11-79A008, dated December 11, 2001.
Note 1: Boeing Alert Service Bulletin MD11-79A008 refers to
Pratt & Whitney Alert Service Bulletin PW4MD11 A79-9, dated October
25, 2001, as an additional source of service information for
replacing the hose assemblies.
Alternative Methods of Compliance (AMOCs)
(g) The Manager, Los Angeles Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
Material Incorporated by Reference
