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 Action Labor cost Parts cost Inspection ........... Up to 36 work-hours × $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. emcdonald on DSK67QTVN1PROD with PROPOSALS Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

AD 2010–23–12 requires inspecting to determine the part number for Thales Avionics Angle of Attack (AoA) probes, and replacing any affected probe with a serviceable probe. Since we issued AD 2010–23–12 we received reports that the AoA sensors on certain airplanes were modified and re-identified without performing the inspection to determine the part number; therefore, the affected probes were not replaced with serviceable probes. This proposed AD would add airplanes to the applicability and, for certain airplanes, require those affected probes be replaced. We are proposing this AD to prevent erroneous AoA information and consequent delayed activation or non-activation of the AoA protection systems, which, in combination with flight at a high angle of attack, could result in reduced controllability of the airplane.

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.

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:

                                    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:

[[Page 59295]]

(a) Comments Due Date

    We must receive comments by November 12, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 777-200, -200LR, -
300, -300ER, and -777F series airplanes, certificated in any 
category, as identified in Boeing Alert Service Bulletin 777-
53A0068, dated June 12, 2013.

 (d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by a report of cracking in the fuselage 
skin underneath the satellite communication (SATCOM) antenna 
adapter. We are issuing 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections

    (1) For Group 1-4 airplanes and Group 5, Configuration 3 and 4 
airplanes identified in Boeing Alert Service Bulletin 777-53A0068, 
dated June 12, 2013: Except as required by paragraphs (h)(1) and 
(h)(2) of this AD, within the applicable compliance times specified 
in paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 
777-53A0068, dated June 12, 2013, do internal detailed and surface 
high frequency eddy current (HFEC) inspections of the visible 
fuselage skin, and doubler if installed, for cracking; do external 
detailed and surface HFEC inspections of the visible fuselage skin, 
and doubler if installed, for cracking, corrosion, and any 
indication that shows a contact of a certain fastener to a bonding 
jumper; and do all applicable repairs; in accordance with the 
Accomplishment Instructions of Boeing Alert Service Bulletin 777-
53A0068, dated June 12, 2013, except as required by paragraph (h)(3) 
of this AD. Thereafter, repeat the inspections at the applicable 
intervals specified in paragraph 1.E., ``Compliance,'' of Boeing 
Alert Service Bulletin 777-53A0068, dated June 12, 2013. Do all 
applicable repairs before further flight.
    (2) For Group 5, Configuration 1, 2, and 5 airplanes identified 
in Boeing Alert Service Bulletin 777-53A0068, dated June 12, 2013: 
No action is required by this AD.

(h) Exceptions to the Service Information

    (1) The ``Condition Questionnaire'' column in Tables 1, 5, and 9 
of paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 
777-53A0068, dated June 12, 2013, refers to airplanes with certain 
conditions ``at the time of the original issue date of this service 
bulletin.'' For this AD, use ``as of the effective date of this AD'' 
instead of ``at the time of the original issue date of this service 
bulletin.''
    (2) Where paragraph 1.E., ``Compliance,'' of Boeing Alert 
Service Bulletin 777-53A0068, dated June 12, 2013, specifies a 
compliance time ``after the original issue date of this service 
bulletin,'' this AD requires compliance within the specified 
compliance time after the effective date of this AD.
    (3) If any crack, corrosion, or indication that shows a contact 
of the fastener attaching the SATCOM lug adapter plate to the 
bonding plate is found during any inspection required by this AD, 
and Boeing Alert Service Bulletin 777-53A0068, dated June 12, 2013, 
specifies to contact Boeing for repair instructions: Before further 
flight, repair using a method approved in accordance with the 
procedures specified in paragraph (i) of this AD.

 (i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in the Related Information 
section of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Seattle ACO, to make 
those findings. For a repair method to be approved, the repair must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
