SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on February 22, 2012 (77 FR 10411). That NPRM proposed to require repetitive external phased-array ultrasonic inspections to detect cracks of the affected fuselage skin lap splices in Sections 41, 43, and 44, as applicable, and repair if necessary. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (77 FR 10411, February 22, 2012) and the FAA’s response to each comment. Request To Allow Certain Repairs Boeing requested we add additional text to the end of paragraph (h)(2) of the NPRM (77 FR 10411, February 22, 2012) stating ‘‘* * * unless all cracked material has been completely removed and the repair is a reinforcing repair that has been FAA approved to [Federal 42963 Aviation Regulations] 14 CFR 25.571 and 14 CFR 26.43 (c) or (d).’’ Boeing stated that reinforcing repairs which are FAA approved to 14 CFR 25.571 at the certification basis for the subject Model 777 airplanes and 14 CFR 26.43(c) or (d) must have been evaluated for damage tolerance, and would have the damage tolerance inspection requirements in place in order to maintain the safety of the airplane at the repaired area. Boeing asserted that the requirement to obtain an alternative method of compliance (AMOC) approval for such repairs would therefore not be required to ensure the safety of the repaired airplane. We disagree. The change proposed by Boeing would only require compliance for two certain regulations and would not require other necessary regulatory standards. The requirements defined in the existing AMOC delegation authority include other FAA regulations and manufacturer’s design considerations beyond those listed on the airplane type certificate data sheet. We have not changed the final rule in this regard. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD affects 46 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Inspections for Group 1 airplanes (25 airplanes). Inspections for Group 2 airplanes (21 airplanes). Labor cost 126 work-hours × $85 per hour = $10,710 per inspection cycle. 50 work-hours × $85 per hour = $4,250 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the on-condition repair. mstockstill on DSK4VPTVN1PROD with RULES 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.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on February 22, 2012 (77 FR 
10411). That NPRM proposed to require repetitive external phased-array 
ultrasonic inspections to detect cracks of the affected fuselage skin 
lap splices in Sections 41, 43, and 44, as applicable, and repair if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 10411, February 22, 2012) and the FAA's response to each 
comment.

Request To Allow Certain Repairs

    Boeing requested we add additional text to the end of paragraph 
(h)(2) of the NPRM (77 FR 10411, February 22, 2012) stating ``* * * 
unless all cracked material has been completely removed and the repair 
is a reinforcing repair that has been FAA approved to [Federal Aviation 
Regulations] 14 CFR 25.571 and 14 CFR 26.43 (c) or (d).'' Boeing stated 
that reinforcing repairs which are FAA approved to 14 CFR 25.571 at the 
certification basis for the subject Model 777 airplanes and 14 CFR 
26.43(c) or (d) must have been evaluated for damage tolerance, and 
would have the damage tolerance inspection requirements in place in 
order to maintain the safety of the airplane at the repaired area. 
Boeing asserted that the requirement to obtain an alternative method of 
compliance (AMOC) approval for such repairs would therefore not be 
required to ensure the safety of the repaired airplane.
    We disagree. The change proposed by Boeing would only require 
compliance for two certain regulations and would not require other 
necessary regulatory standards. The requirements defined in the 
existing AMOC delegation authority include other FAA regulations and 
manufacturer's design considerations beyond those listed on the 
airplane type certificate data sheet. We have not changed the final 
rule in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Costs of Compliance

    We estimate that this AD affects 46 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

provide cost estimates for the on-condition repair.

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.

[[Page 42964]]

    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.
