ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747–100, –100B, –100B SUD, –200B, –200C, –200F, –300, –400, –400D, –400F, and 747SR series airplanes. This AD was prompted by reports of cracking at the aft upper corner of the main entry door (MED) 5 cutout. This AD requires inspecting for the presence of repairs and measuring the edge margin at certain fastener locations around the upper aft corner of the door cutout, inspecting for any cracking of the fuselage skin assembly and bear strap in the aft upper corner area of the door cutout, and repairing or modifying the fuselage skin assembly and bear strap if necessary. We are issuing this AD to detect and correct cracking of the skin and bear straps at the aft upper corner of the MED 5 cutout, which could result in in-flight depressurization. DATES: This final rule is effective November 6, 2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 6, 2013.

SUMMARY: Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD Frm 00018 Fmt 4700 Sfmt 4700 E:\FR\FM\02OCR1.SGM 02OCR1 Federal Register / Vol. 78, No. 191 / Wednesday, October 2, 2013 / Rules and Regulations docket contains this AD, the regulatory evaluation, any comments received, and other information.

SUPPLEMENTARY INFORMATION: 53A2839, dated November 6, 2012, specifies the installation of a preventative modification, with the option of doing the repetitive inspections until installation of the preventative modification. UPS added that it is not intuitively clear that corrective action is required for the case where no cracks are found. We agree that clarification is necessary. We have revised the phrasing and paragraph structure of paragraph (g)(2) of this final rule to clarify what is required or acceptable in the case of no crack findings. However, we have not used the phrase ‘‘applicable corrective or additional actions’’ as suggested by UPS. 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 March 28, 2013 (78 FR 18917). The NPRM proposed to require inspecting for the presence of repairs and measuring the edge margin at certain fastener locations around the upper aft corner of the door cutout, inspecting for any cracking of the fuselage skin assembly and bear strap in the aft upper corner area of the door cutout, and repairing or modifying the fuselage skin assembly and bear strap if necessary. Request To Add Option To Do Certain Actions by Using Service Information Boeing requested that paragraph (g)(1) of the NPRM (78 FR 18917, March 28, 2013) be revised to refer to Boeing Alert Service Bulletin 747–53A2839, dated November 6, 2012, for instructions instead of referencing the alternative method of compliance (AMOC) process. Boeing referred to similar language in the last sentence of paragraph (g)(2) of the NPRM and suggested adding that language to paragraph (g)(1) of the NPRM would clarify the required actions. We disagree. For the condition addressed by paragraph (g)(1) of this final rule, Boeing Alert Service Bulletin 747–53A2839, dated November 6, 2012, states to ‘‘Do inspections or change the repair, as described by Boeing.’’ To require operators to contact Boeing for these actions would be delegating our rulemaking authority to the manufacturer. Paragraph (h)(2) of this final rule also requires using the AMOC process instead where Boeing Alert Service Bulletin 747–53A2839, dated November 6, 2012, specifies to contact Boeing. We have not changed this final rule in this regard. sroberts on DSK5SPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (78 FR 18917, March 28, 2013) and the FAA’s response to each comment. Request To Provide Clarification or Revision of Corrective Actions Phrase in Paragraph (g)(2) of the NPRM (78 FR 18917, March 28, 2013) UPS requested that the phrase ‘‘applicable corrective or additional actions’’ be used in place of ‘‘applicable corrective actions’’ in paragraph (g)(2) of the NPRM (78 FR 18917, March 28, 2013). UPS found the use of ‘‘applicable corrective actions’’ to be confusing in the case when no cracks are found during the inspection and stated the phrase could lead to problems with interpretation. UPS stated that for airplanes on which no cracks are found, Boeing Alert Service Bulletin 747– VerDate Mar<15>2010 15:59 Oct 01, 2013 Jkt 232001 Request To Approve an Alternate Generic Repair Scheme as an AMOC British Airways requested that an alternate generic repair scheme be approved as an AMOC to this final rule. British Airways stated that it is in favor of doing the detailed inspections for the presence of repairs and measuring the edge margin, as it has had several findings during the accomplishment of Boeing Alert Service Bulletin 747– 53A2839, dated November 6, 2012. PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 60671 However, due to insufficient availability of the modification kit (due to the service bulletin validation process), Boeing had provided an alternate generic repair scheme to British Airways which allowed British Airways to manufacture certain repair parts. British Airways stated it has requested that Boeing include the alternate generic repair scheme in the next revision of Boeing Alert Service Bulletin 747– 53A2839, dated November 6, 2012. We disagree. An AMOC is issued only after an AD has been issued and only after data are provided to show that the proposed solution is complete and addresses the unsafe condition. The alternate generic repair scheme that British Airways attached to its comment states that the ‘‘repair is generic, and may need to be modified to account for the existing configuration and reported conditions.’’ Therefore, each repair will need to be evaluated on a case-by-case basis. Once we issue this final rule, anyone may submit an AMOC request to use an alternate generic repair scheme under the provisions of paragraph (j) of this final rule. Sufficient data must be submitted to substantiate the generic repair and show that it 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 changes 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 18917, March 28, 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 18917, March 28, 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 246 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\02OCR1.SGM 02OCR1 60672 Federal Register / Vol. 78, No. 191 / Wednesday, October 2, 2013 / Rules and Regulations ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspect for repair and measure edge margin. 1 work-hour × $85 per hour = $85 per door (up to 2 doors per airplane). None ................. Up to $170 ....... Up to $41,820. We estimate the following costs to do any necessary repetitive inspections, repairs or modifications 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 inspections, repairs or modification: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Repetitive inspections of un-repaired area. 6 work-hours × $85 per hour = $510 per door, per inspection cycle. 10 work-hours × $85 per hour = $850 per door. None ............................................. $510 per door, per inspection cycle. Between $7,654 and $17,426 per door. Between $8,504 and $18,276 per door. Repair or modification .................... 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. sroberts on DSK5SPTVN1PROD with RULES 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 15:59 Oct 01, 2013 Jkt 232001 (d) Subject Joint Aircraft System Component (JASC)/ Air Transport Association (ATA) of America Code 53, Fuselage.

200F, -300, -400, -400D, -400F, and 747SR series airplanes. This AD was 
prompted by reports of cracking at the aft upper corner of the main 
entry door (MED) 5 cutout. This AD requires inspecting for the presence 
of repairs and measuring the edge margin at certain fastener locations 
around the upper aft corner of the door cutout, inspecting for any 
cracking of the fuselage skin assembly and bear strap in the aft upper 
corner area of the door cutout, and repairing or modifying the fuselage 
skin assembly and bear strap if necessary. We are issuing this AD to 
detect and correct cracking of the skin and bear straps at the aft 
upper corner of the MED 5 cutout, which could result in in-flight 
depressurization.

DATES: This final rule is effective November 6, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 6, 
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 March 28, 2013 (78 FR 18917). 
The NPRM proposed to require inspecting for the presence of repairs and 
measuring the edge margin at certain fastener locations around the 
upper aft corner of the door cutout, inspecting for any cracking of the 
fuselage skin assembly and bear strap in the aft upper corner area of 
the door cutout, and repairing or modifying the fuselage skin assembly 
and bear strap if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(78 FR 18917, March 28, 2013) and the FAA's response to each comment.

Request To Provide Clarification or Revision of Corrective Actions 
Phrase in Paragraph (g)(2) of the NPRM (78 FR 18917, March 28, 2013)

    UPS requested that the phrase ``applicable corrective or additional 
actions'' be used in place of ``applicable corrective actions'' in 
paragraph (g)(2) of the NPRM (78 FR 18917, March 28, 2013). UPS found 
the use of ``applicable corrective actions'' to be confusing in the 
case when no cracks are found during the inspection and stated the 
phrase could lead to problems with interpretation. UPS stated that for 
airplanes on which no cracks are found, Boeing Alert Service Bulletin 
747-53A2839, dated November 6, 2012, specifies the installation of a 
preventative modification, with the option of doing the repetitive 
inspections until installation of the preventative modification. UPS 
added that it is not intuitively clear that corrective action is 
required for the case where no cracks are found.
    We agree that clarification is necessary. We have revised the 
phrasing and paragraph structure of paragraph (g)(2) of this final rule 
to clarify what is required or acceptable in the case of no crack 
findings. However, we have not used the phrase ``applicable corrective 
or additional actions'' as suggested by UPS.

Request To Add Option To Do Certain Actions by Using Service 
Information

    Boeing requested that paragraph (g)(1) of the NPRM (78 FR 18917, 
March 28, 2013) be revised to refer to Boeing Alert Service Bulletin 
747-53A2839, dated November 6, 2012, for instructions instead of 
referencing the alternative method of compliance (AMOC) process. Boeing 
referred to similar language in the last sentence of paragraph (g)(2) 
of the NPRM and suggested adding that language to paragraph (g)(1) of 
the NPRM would clarify the required actions.
    We disagree. For the condition addressed by paragraph (g)(1) of 
this final rule, Boeing Alert Service Bulletin 747-53A2839, dated 
November 6, 2012, states to ``Do inspections or change the repair, as 
described by Boeing.'' To require operators to contact Boeing for these 
actions would be delegating our rulemaking authority to the 
manufacturer. Paragraph (h)(2) of this final rule also requires using 
the AMOC process instead where Boeing Alert Service Bulletin 747-
53A2839, dated November 6, 2012, specifies to contact Boeing. We have 
not changed this final rule in this regard.

Request To Approve an Alternate Generic Repair Scheme as an AMOC

    British Airways requested that an alternate generic repair scheme 
be approved as an AMOC to this final rule. British Airways stated that 
it is in favor of doing the detailed inspections for the presence of 
repairs and measuring the edge margin, as it has had several findings 
during the accomplishment of Boeing Alert Service Bulletin 747-53A2839, 
dated November 6, 2012. However, due to insufficient availability of 
the modification kit (due to the service bulletin validation process), 
Boeing had provided an alternate generic repair scheme to British 
Airways which allowed British Airways to manufacture certain repair 
parts. British Airways stated it has requested that Boeing include the 
alternate generic repair scheme in the next revision of Boeing Alert 
Service Bulletin 747-53A2839, dated November 6, 2012.
    We disagree. An AMOC is issued only after an AD has been issued and 
only after data are provided to show that the proposed solution is 
complete and addresses the unsafe condition. The alternate generic 
repair scheme that British Airways attached to its comment states that 
the ``repair is generic, and may need to be modified to account for the 
existing configuration and reported conditions.'' Therefore, each 
repair will need to be evaluated on a case-by-case basis. Once we issue 
this final rule, anyone may submit an AMOC request to use an alternate 
generic repair scheme under the provisions of paragraph (j) of this 
final rule. Sufficient data must be submitted to substantiate the 
generic repair and show that it 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 changes described previously--and minor editorial 
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM (78 FR 18917, March 28, 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 18917, March 28, 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 246 airplanes of U.S. registry.
    We estimate the following costs to comply with 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.
