Airworthiness Directives; Boeing Model 757-200 and -200CB Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain Boeing Model 757-200 series airplanes, that
currently requires modifications to the attachment installation of the
forward lavatory. This amendment adds airplanes to the applicability of
the existing AD. The actions specified by this AD are intended to
prevent failure of the attachment installation of the forward lavatory
during an emergency landing, which could result in injury to the crew
and passengers. This action is intended to address the identified
unsafe condition.
DATES: Effective May 5, 2004.
The incorporation by reference of Boeing Special Attention Service
Bulletin 757-25-0181, Revision 1, dated November 21, 2000, as listed in
the regulations, is approved by the Director of the Federal Register as
of May 5, 2004.
The incorporation by reference of Boeing Service Bulletin 757-25-
0181, dated June 26, 1997; and Boeing Alert Service Bulletin 757-
25A0187, dated September 18, 1997; as listed in the regulations, was
approved previously by the Director of the Federal Register as of June
1, 1999 (64 FR 20146, April 26, 1999).
ADDRESSES: The service information referenced in this AD may be
obtained from Boeing Commercial Airplanes, P.O. Box 3707, Seattle,
Washington 98124-2207. This information may be examined at the Federal
Aviation Administration (FAA), Transport Airplane Directorate, Rules
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of
the Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.
FOR FURTHER INFORMATION CONTACT: David Crotty, Aerospace Engineer,
Cabin Safety and Environmental Systems Branch, ANM-150S, FAA, Seattle
Aircraft Certification Office, 1601 Lind Avenue, SW., Renton,
Washington 98055-4056; telephone (425) 917-6422; fax (425) 917-6590.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 99-09-13,
amendment 39-11146 (64 FR 20146, April 26, 1999), which is applicable
to certain Boeing Model 757-200 series airplanes, was published in the
Federal Register on December 22, 2003 (68 FR 71051). The action
proposed to continue to require modifications to the attachment
installation of the forward lavatory. The action also proposed to add
airplanes to the applicability of the existing AD.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
There are approximately 694 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 355 airplanes of U.S. registry
will be affected by this AD.
It will take approximately 4 work hours per airplane to accomplish
the required modification, at an average labor rate of $65 per work
hour. Required parts will cost approximately $100 per airplane. Based
on these figures, the cost impact of the required
[[Page 16787]]
modification on U.S. operators is estimated to be $127,800, or $360 per
airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions. The manufacturer may cover the cost of
replacement parts associated with this AD, subject to warranty
conditions. Manufacturer warranty remedies may also be available for
labor costs associated with this AD. As a result, the costs
attributable to the AD may be less than stated above.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
