Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 777 airplanes. This AD was prompted by a 
report of cracking in the fuselage skin underneath the satellite 
communication (SATCOM) antenna adapter. This AD requires 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 issuing 
this AD to detect and correct cracking and corrosion in the fuselage 
skin, which could lead to rapid decompression and

[[Page 12376]]

loss of structural integrity of the airplane.

DATES: This AD is effective April 9, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 9, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company 
Model 777 airplanes. The NPRM published in the Federal Register on 
September 26, 2013 (78 FR 59293). The NPRM was prompted by a report of 
cracking in the fuselage skin underneath the satellite communication 
(SATCOM) antenna adapter. The NPRM proposed to 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 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(78 FR 59293, September 26, 2013) and the FAA's response to each 
comment.

Request To Revise Paragraph (h)(1) of the NPRM (78 FR 59293, September 
26, 2013) To Include Footnotes

    Boeing requested that paragraph (h)(1) of the NPRM (78 FR 59293, 
September 26, 2013) be revised to include the footnotes to Tables 1, 5, 
and 9 of paragraph 1.E. ``Compliance,'' in addition to the 
``Questionnaire Column,'' specified in Boeing Alert Service Bulletin 
777-53A0068, dated June 12, 2013. Boeing stated that the statement, 
``at the time of the original issue date of this service bulletin'' is 
not only used in the ``Condition Questionnaire'' column of Tables 1, 5, 
and 9 of paragraph 1.E. ``Compliance,'' but it is also used in the 
footnotes.
    We agree with Boeing's request. We have revised paragraph (h)(1) of 
this final rule by removing the phrase ``the `Condition Questionnaire' 
column in'' so that the exception applies to the entire table including 
the footnotes.

Request To Revise Paragraph (h)(1) of the NPRM (78 FR 59293, September 
26, 2013) To Include the Compliance Time Column of Tables 2 Through 12

    American Airlines (AA) requested that paragraph (h)(1) of the NPRM 
(78 FR 59293, September 26, 2013) be revised to include exceptions for 
the footnotes in Tables 1, 5, and 9, and the compliance times in Tables 
2, 3, 4, 6, 7, 8, 10, 11, and 12, as specified in Boeing Alert Service 
Bulletin 777-53A0068, dated June 12, 2013. AA stated that paragraph 
(h)(1) of the NPRM creates exceptions to the service information in 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, in that it allows a change in wording from ``. . . at 
the time of the original issue of this service bulletin'' to ``. . . as 
of the effective date of this AD.'' AA stated that this exception 
should be allowed for Tables 2 through 12 of paragraph 1.E. 
``Compliance,'' of Boeing Alert Service Bulletin 777-53A0068, dated 
June 12, 2013.
    We partially agree with AA's request. As stated previously, we have 
revised paragraph (h)(1) of this final rule to address the footnotes in 
Tables 1, 5, and 9, of paragraph 1.E. ``Compliance,'' of Boeing Alert 
Service Bulletin 777-53A0068, dated June 12, 2013. However, paragraph 
(h)(2) of this final rule already provides the exception for certain 
compliance times for Tables 2, 3, 4, 6, 7, 8, 10, 11, and 12, of 
paragraph 1.E. ``Compliance,'' of Boeing Alert Service Bulletin 777-
53A0068, dated June 12, 2013. Therefore, no change is necessary to the 
final rule in this regard.

Request To Add a Terminating Action

    FedEx requested that a terminating action be added prior to the 
release of the final rule. FedEx stated that Boeing should revise 
Boeing Alert Service Bulletin 777-53A0068, dated June 12, 2013, to 
include a terminating action. FedEx stated that although the initial 
inspection can be planned during a scheduled maintenance visit, the 
repetitive inspections will require additional, unscheduled, and out of 
service time. FedEx also stated that the terminating action would 
alleviate any additional maintenance, scheduled or otherwise.
    We disagree. We do not consider that delaying this action until 
after the release of new service information is warranted. We do not 
agree to delay this final rule while a terminating action is being 
developed due to the unsafe condition that exists. However, under the 
provisions of paragraph (i)(1) of this final rule, we will consider 
alternative methods of compliance if sufficient data are submitted to 
substantiate that the change would provide an acceptable level of 
safety. We have not changed this final rule in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the change described previously, and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 59293, September 26, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 59293, September 26, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 120 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
         Action                Labor cost           Parts cost       Cost per product     Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection.............  Up to 36 work-hours x               $0   Up to $3,060 per        Up to $367,200 per
                          $85 per hour = $3,060                    inspection cycle.       inspection cycle.
                          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 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

    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),
    (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.
