14 CFR Part 39

[Docket No. FAA-2012-0804; Directorate Identifier 2012-NM-094-AD; 
Amendment 39-17316; AD 2013-01-02]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 
747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 
747SR, and 747SP series airplanes; and certain Model 757-200, -200PF, 
and -300 series airplanes. That AD currently requires replacing the 
control switches of the forward, aft, and nose cargo doors of Model 747 
airplanes; and requires replacing the control switches of cargo doors 1 
and 2 of Model 757 series airplanes. This new AD adds airplanes to the 
applicability and revises the initial compliance times for those 
airplanes. This AD was prompted by reports of problems associated with 
the uncommanded operation of cargo doors. We are issuing this AD to 
prevent injuries to persons and damage to the airplane and equipment.

DATES: This AD is effective February 22, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of February 22, 
2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of 
December 3, 2009 (74 FR 55763, October 29, 2009).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2009-22-08, Amendment 39-16059 (74 FR 55763, 
October 29, 2009). That AD applies to the specified products. The NPRM 
published in the Federal Register on August 3, 2012 (77 FR 46343). That 
NPRM proposed to continue to require replacing the control switches of 
the forward, aft, and nose cargo doors of Model 747 airplanes; and the 
control switches of cargo doors 1 and 2 of Model 757 airplanes. That 
NPRM also proposed to add airplanes to the applicability and to revise 
the initial compliance times for those airplanes.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 46343, August 3, 2012) and the FAA's response to each comment.

Support for the NPRM (77 FR 46343, August 3, 2012)

    Boeing supported the NPRM (77 FR 46343, August 3, 2012).
    American Airlines found that the NPRM (77 FR 46343, August 3, 2012) 
would not require additional actions for its Model 757 fleet; 
therefore, American Airlines had no comments concerning the NPRM.

Request for Clarification of Proposed Compliance Times

    Asiana Airlines requested that we clarify the compliance times 
specified in paragraph (g) of the NPRM (77 FR 46343, August 3, 2012). 
Specifically, Asiana Airlines requested clarification of the compliance 
times for Model 747 Groups 1 and 2 airplanes on which the door switches 
had been replaced before the effective date of AD 2009-22-08, Amendment 
39-16059 (74 FR 55763, October 29, 2009), per Boeing Special Attention 
Service Bulletin 747-52-2286, dated September 28, 2007; and on which 
the certificate of airworthiness had been issued long before 72 months 
after the effective date of AD 2009-22-08.
    We agree to provide clarification. Paragraph (g)(1) of this AD 
restates the compliance time from AD 2009-22-08, Amendment 39-16059 (74 
FR 55763, October 29, 2009) for Groups 1 and 2 Model 747 airplanes 
identified in Boeing Special Attention Service Bulletin 747-52-2286, 
Revision 1, dated October 28, 2010. If an operator has already replaced 
the switches before the effective date of this AD in accordance with 
either Boeing Special Attention Service Bulletin 747-52-2286, dated 
September 28, 2007; or Boeing Special Attention Service Bulletin 747-
52-2286, Revision 1, dated October 28, 2010; then no further action is 
necessary for compliance with paragraph (g) of this AD. No change to 
this AD is necessary.

Explanation of Change Made to This AD

    We have added new paragraph (i)(3) to this final rule to allow 
delegation of repairs to the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA). We have re-identified subsequent 
paragraphs accordingly.

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--and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 46343, August 3, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 46343, August 3, 2012).

Costs of Compliance

    We estimate that this AD affects 225 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

    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 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

    We have determined that 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.

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.
