14 CFR Part 39
[Docket No. FAA-2006-24978; Directorate Identifier 2006-NM-108-AD;
Amendment 39-15113; AD 2007-13-09]
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
modifying the fuel boost pump container of the center tank. This AD
results from fuel system reviews conducted by the manufacturer. We are
issuing this AD to prevent exposing the fuel pump container vapor area
to electrical arcing during a fuel pump motor case or connector burn
through, which could result in a fuel tank explosion.
[[Page 35641]]
DATES: This AD becomes effective August 3, 2007.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of August 3,
2007.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Operations office between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal holidays. The Docket Operations
office (telephone (800) 647-5527) is located on the ground floor of the
West Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to certain
McDonnell Douglas Model 717-200 airplanes. That supplemental NPRM was
published in the Federal Register on April 30, 2007 (72 FR 21169). That
supplemental NPRM proposed to require modifying the fuel boost pump
container of the center tank. That supplemental NPRM also proposed to
add airplanes to the applicability.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Clarification of Alternative Method of Compliance (AMOC) Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the AD.
Costs of Compliance
There are about 145 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 and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
