Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2004-19987; Directorate Identifier 2004-NM-203-AD;
Amendment 39-14105; AD 2005-11-03]
RIN 2120-AA64
Airworthiness Directives; McDonnell Douglas Model 717-200
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain McDonnell Douglas Model 717-200 airplanes. This AD requires
replacing eight brake fuses of the hydraulic quantity limiter with new
or modified and reidentified fuses. This AD is prompted by reports
indicating that brake fuses of the hydraulic quantity limiter of the
main landing gear have failed. We are issuing this AD to prevent loss
of both hydraulic and brake systems if one fuse on each hydraulic
system were to fail simultaneously, and consequent reduced
controllability of the airplane.
DATES: This AD becomes effective July 1, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of July
1, 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).
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-
5227) is located on the plaza level of the Nassif Building at

the U.S. Department of Transportation, 400 Seventh Street SW, room PL-
401, Washington, DC. This docket number is FAA-2004-19987; the
directorate identifier for this docket is 2004-NM-203-AD.

Safety/Mechanical and Environmental Systems Branch, ANM-150L, FAA, Los
Angeles Aircraft Certification Office, 3960 Paramount Boulevard,
Lakewood, California 90712-4137; telephone (562) 627-5346; fax (562)
627-5210.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for certain McDonnell Douglas Model 717-200 airplanes. That
action, published in the Federal Register on January 5, 2005 (70 FR
731), proposed to require replacing eight brake fuses of the hydraulic
quantity limiter with new or modified and reidentified fuses.
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.
Support for Proposed AD
One commenter supports the proposed AD.
Request to Refer to Vendor Part Numbers
One commenter has no technical objection to the proposed AD, but
would like the vendor part numbers to be included with the Boeing part
numbers in paragraphs (g) and (h) of the proposed AD. The commenter
provided no justification for its request.
We do not agree. Paragraph (g) of the AD refers to Boeing Alert
Service Bulletin 717-32A0031, dated September 10, 2004, as the
appropriate source of service information for accomplishing the
required replacement. Note (a) of paragraph 2.C.1. of the service
bulletin identifies the vendor part numbers that correspond to the
Boeing part numbers referenced in the AD. Therefore, we find it
unnecessary to specify vendor part numbers in either paragraph (g) or
(h) of the AD when the referenced service bulletin contains that
information. We have made no change to the AD in this regard.
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 133 airplanes of the affected design in the
worldwide fleet and 103 airplanes on the U.S. registry. The following
table provides the estimated costs for U.S. operators to comply with
this AD.
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Average labor Cost per
Action Work hours rate per hour Parts airplane
----------------------------------------------------------------------------------------------------------------
Option 1. Replacement with new brake 9 $65 No Charge................ $585
fuses.
Option 2. Replacement with modified 13 65 No Charge................ 845
and reidentified brake fuses.
----------------------------------------------------------------------------------------------------------------
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.
