14 CFR Part 39
[Docket No. FAA-2013-0830; Directorate Identifier 2013-NM-128-AD]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain The Boeing Company Model 777 airplanes. This proposed AD was
prompted by a report of cracking in the fuselage skin underneath the
satellite communication (SATCOM) antenna adapter. This proposed AD
would require repetitive inspections of the visible fuselage skin and
doubler if installed, for cracking, corrosion, and any indication of
contact of a certain fastener to a bonding jumper, and repair if
necessary. We are proposing this AD to detect and correct cracking and
corrosion in the fuselage skin, which could lead to rapid decompression
and loss of structural integrity of the airplane.
DATES: We must receive comments on this proposed AD by November 12,
2013.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2013-0830;
Directorate Identifier 2013-NM-128-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We

Discussion
We received a report of cracking and corrosion in the fuselage skin
underneath the SATCOM antenna adapter. During a maintenance planning
data inspection, one operator reported a 16-inch crack under the 3-bay
SATCOM antenna adapter plate in the crown skin of the fuselage on an
airplane that was 14 years old with approximately 14,000 total flight
cycles. Subsequent to this crack finding, the same operator inspected
42 other airplanes that are between 6 and 16 years old and found some
local corrosion, but no other cracking. Cracking and corrosion in the
fuselage skin, if not corrected, could lead to rapid decompression and
loss of structural integrity of the airplane.
Relevant Service Information
We reviewed Boeing Alert Service Bulletin 777-53A0068, dated June
12, 2013. For information on the procedures and compliance times, see
this service information at http://www.regulations.gov by searching for
Docket No. FAA-2013-0830.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described previously, except as discussed
under ``Differences Between the Proposed AD and the Service
Information.''
Differences Between the Proposed AD and the Service Information
The service bulletin specifies to contact the manufacturer for
instructions on how to repair certain conditions, but this proposed AD
would require repairing those conditions in one of the following ways:
In accordance with a method that we approve; or
Using data that meet the certification basis of the
airplane, and that have been approved by the Boeing Commercial
Airplanes Organization Designation Authorization (ODA) whom we have
authorized to make those findings.
Costs of Compliance
We estimate that this proposed AD affects 120 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection....................... Up to 36 $0 Up to $3,060 per Up to $367,200 per
work[dash]hours x inspection cycle. inspection cycle.
$85 per hour =
$3,060 per
inspection cycle.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
