Amendment 39-17639; AD 2013-22-07]

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 747-400 series airplanes. This AD was prompted 
by reports of fasteners missing on an airplane undergoing a passenger-
to-freighter conversion. This AD requires doing a general visual 
inspection of the station 1920 splice clip for correct fastener 
installation, and related investigative and corrective actions if 
necessary. We are issuing this AD to detect and correct missing or 
incorrect fasteners, which can lead to cracking and loss of load 
carrying capacity, resulting in a possible decompression event.

DATES: This AD is effective December 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 5, 
2013.

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 the specified products. The 
NPRM published in the Federal Register on August 1, 2013 (78 FR 46540). 
The NPRM proposed to require doing a general visual inspection of the 
station 1920 splice clip for correct fastener installation, and related 
investigative and corrective actions if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received. The Boeing Company 
supports the NPRM (78 FR 46540, August 1, 2013).

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed--except for minor editorial changes. We have 
determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (78 FR 46540, August 1, 2013) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 46540, August 1, 2013).

Costs of Compliance

    We estimate that this AD affects 3 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.

 installation.                         hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the inspection. We have no 
way of determining the number of aircraft that might need these 
repairs:

                                               On-Condition Costs

Fastener installation.........................  2 work-hours x $85 per hour =                  0             170
                                                 $170.
Repair........................................  2 work-hours x $85 per hour =                  0             170
                                                 $170.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we

[[Page 65172]]

have included all costs in our cost estimate.

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.

action: Before further flight, repair using a method approved in 
accordance with the procedures specified in paragraph (j) of this 
AD.

(g) of this AD, if those actions were performed before the effective 
date of this AD using Boeing Alert Service Bulletin 747-53A2844, 
dated September 15, 2011, except the detailed inspection for 
cracking of the auxiliary sill outer chord tee and attached parts 
and all applicable related investigative and corrective actions must 
be done in accordance with Boeing Alert Service Bulletin 747-
53A2844, Revision 1, dated July 30, 2012, at the times specified in 
paragraph (g) of this AD. Boeing Alert Service Bulletin 747-53A2844, 
dated September 15, 2011, is not incorporated by reference in this 
AD.

(j) 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 paragraph (k) of this AD. 
Information may be emailed to: <a href="/cdn-cgi/l/email-protection#e7decaa6a9aacab4828693938b82caa6a4a8caa6aaa8a4cab582969282949394a7818686c9808891"><span class="__cf_email__" data-cfemail="88b1a5c9c6c5a5dbede9fcfce4eda5c9cbc7a5c9c5c7cba5daedf9fdedfbfcfbc8eee9e9a6efe7fe">[email&#160;protected]</span></a>.
    (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
