Airworthiness Directives; The Boeing Company Model 757 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Model 757 airplanes. This AD requires changing the lower fixed leading
edge panel assemblies immediately outboard of the nacelles at slats 4
and 7. This AD results from reports of Model 757 airplanes in service
that have drain holes and unsealed panel assemblies in the fixed
leading edge adjacent to the inboard end of slats 4 and 7 that are too
close to the hot portion of the engines. We are issuing this AD to
prevent fuel leaking onto an engine and a consequent fire.
DATES: This AD is effective December 14, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of December 14,
2010.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
all Model 757 airplanes. That NPRM was published in the Federal
Register on June 3, 2010 (75 FR 31329). That NPRM proposed to require
changing the lower fixed leading edge panel assemblies immediately
outboard of the nacelles at slats 4 and 7.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received from the commenters.
Support for Proposed AD
Boeing concurred with the contents of the proposed AD. FedEx,
Continental Airlines, and American Airlines had no technical objection
to changing the lower fixed leading edge panel assemblies immediately
outboard of the nacelles at slats 4 and 7, as specified in the proposed
AD.
Request To Correct Part Number of Washer
FedEx, Continental Airlines, and American Airlines requested that
we correct the part number of a washer used in Figures 1 and 4 of
Boeing Special Attention Service Bulletin 757-57-0070, dated January
27, 2010. The commenters stated that Boeing Service Bulletin
Information Notice 757-57-0070 IN 01, dated March 17, 2010, corrects
the part number of the washer, and that by including this correct part
number in the proposed AD, requests for alternative methods of
compliance (AMOC) will be reduced.
We agree with the request as stated. We have added the correct part
number to paragraph (g) of this AD.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the change described previously. We also determined that
this change will not increase the economic burden on any operator or
increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 697 airplanes of U.S. registry. We
also estimate that it takes 9 work-hours per product to comply with
this AD. The average labor rate is $85 per work-hour. Based on these
figures, we estimate the cost of this AD to the U.S. operators to be
$533,205, or $765 per product.
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
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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
