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 727–200 and 727–200F series airplanes. The NPRM published in the Federal Register on July 18, 2013 (78 FR 42895). This AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. The NPRM proposed to require a one-time inspection for cracking of the pressure floor of both main wheel wells, and related investigative and corrective actions if necessary; and modifying the pressure floor of both main wheel wells. We are issuing this AD to prevent fatigue cracking in the pressure floor of the main wheel wells, which could lead to rapid loss of cabin pressurization. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (78 FR 42895, July 18, 2013) and the FAA’s response to each comment. Request To Clarify the Preamble of the NPRM (78 FR 42895, July 18, 2013) Boeing requested that we clarify the ‘‘Discussion’’ section of the preamble of the NPRM (78 FR 42895, July 18, 2013). Boeing stated that the ‘‘Discussion’’ section in the preamble of the NPRM did not specifically explain that the NPRM is being issued to complete actions in service information that was not previously AD-mandated, but was recommended as a part of the Model 727 airplane service action requirement (SAR) program. Boeing stated that in two places in the ‘‘Discussion’’ section in the NPRM, reference is made to ‘‘certain programs’’ and ‘‘previously established program’’ when it should more specifically refer to the Model 727 airplane SAR program. Additionally, Boeing commented that the focus of the ‘‘Explanation of Compliance Time’’ section in the preamble of the NPRM (78 FR 42895, July 18, 2013) should be on the SAR program instead of on widespread fatigue damage (WFD). However, Boeing stated that the restrictions concerning extensions to compliance times for ADmandated service bulletins related to WFD in the ‘‘Explanation of Compliance Time’’ section in the preamble of the NPRM might be similar to the SAR program. We concur that the NPRM (78 FR 42895, July 18, 2013) references to ‘‘certain programs’’ and ‘‘previously established program’’ are intended to refer to the Model 727 airplane SAR program. However, the ‘‘Discussion’’ section of the NPRM is not restated in this final rule. Therefore, no change to this final rule is necessary in this regard. We find that clarification is necessary concerning how the SAR program and WFD affect this final rule. This final rule is being issued to complete actions in one of the service bulletins recommended as a part of the Model 727 airplane SAR program, but not previously AD-mandated. This is necessary because the LOV for Model 727 series airplanes is dependent on timely completion of the previously established SAR program actions. Since some of those actions, including those mandated by this final rule, were not previously mandated, it is necessary to mandate them now as a part of defining the service actions that support the LOV and preclude WFD. This is the link between WFD and the SAR program actions that were not previously mandated by an AD. Since the requirements of this final rule support the LOV and preclude WFD, the statement that we will not grant any extensions of the compliance time to complete any AD-mandated service information related to WFD without extensive new data applies to this final rule. We have not changed this 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 this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 42895, July 18, 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 42895, July 18, 2013). Costs of Compliance We estimate that this AD affects 94 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators Inspection and Modification ............................ rmajette on DSK2TPTVN1PROD with RULES Action 222 work-hours × $85 per hour = $18,870 .... $2,906 $21,776 $2,046,944 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 VerDate Mar<15>2010 15:17 Feb 21, 2014 Jkt 232001 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 PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 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.

SUPPLEMENTARY INFORMATION: rmajette on DSK2TPTVN1PROD with RULES SUMMARY: History On October 31, 2013, the Federal Aviation Administration (FAA) published in the Federal Register a Notice of Proposed Rulemaking (NPRM) to establish controlled airspace at Brevig Mission Airport, Brevig Mission, AK (78 FR 65239). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. VerDate Mar<15>2010 15:17 Feb 21, 2014 Jkt 232001 Class E airspace designations are published in paragraph 6005, of FAA Order 7400.9X dated August 7, 2013, and effective September 15, 2013, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order. Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist to warrant preparation of an environmental assessment. The Rule This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class E airspace extending upward from 700 feet above the surface at Brevig Mission Airport, Brevig Mission, AK. Controlled airspace extending 2 miles north, 6 miles south, 8 miles southeast and 11 miles northwest of the airport is necessary to accommodate the new RNAV (GPS) standard instrument approach procedures at the airport, and enhances the safety and management of aircraft operations. The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (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); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes controlled airspace at Brevig Mission Airport, Brevig Mission, AK. List of Subjects in 14 CFR Part 71 Airspace, Incorporation by reference, Navigation (air). Adoption of the Amendment In consideration of the foregoing, the FAA amends 14 CFR part 71 as follows: PART 71—DESIGNATION OF CLASS A, B, C, D AND E AIRSPACE AREAS; AIR TRAFFIC SERVICE ROUTES; AND REPORTING POINTS 1.

the airplane reaching its limit of validity (LOV) of the engineering 
data that support the established structural maintenance program. This 
AD requires a one-time inspection for cracking of the pressure floor of 
both main wheel wells, and related investigative and corrective actions 
if necessary; and modifying the pressure floor of both main wheel 
wells. We are issuing this AD to prevent fatigue cracking in the 
pressure floor of the main wheel wells, which could lead to rapid loss 
of cabin pressurization.

DATES: This AD is effective March 31, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 13, 
1991 (56 FR 57233, November 8, 1991).

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 727-200 and 727-200F series airplanes. The NPRM published in the 
Federal Register on July 18, 2013 (78 FR 42895). This AD is intended to 
complete certain mandated programs intended to support the airplane 
reaching its limit of validity (LOV) of the engineering data that 
support the established structural maintenance program. The NPRM 
proposed to require a one-time inspection for cracking of the pressure 
floor of both main wheel wells, and related investigative and 
corrective actions if necessary; and modifying the pressure floor of 
both main wheel wells. We are issuing this AD to prevent fatigue 
cracking in the pressure floor of the main wheel wells, which could 
lead to rapid loss of cabin pressurization.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(78 FR 42895, July 18, 2013) and the FAA's response to each comment.

Request To Clarify the Preamble of the NPRM (78 FR 42895, July 18, 
2013)

    Boeing requested that we clarify the ``Discussion'' section of the 
preamble of the NPRM (78 FR 42895, July 18, 2013). Boeing stated that 
the ``Discussion'' section in the preamble of the NPRM did not 
specifically explain that the NPRM is being issued to complete actions 
in service information that was not previously AD-mandated, but was 
recommended as a part of the Model 727 airplane service action 
requirement (SAR) program. Boeing stated that in two places in the 
``Discussion'' section in the NPRM, reference is made to ``certain 
programs'' and ``previously established program'' when it should more 
specifically refer to the Model 727 airplane SAR program.
    Additionally, Boeing commented that the focus of the ``Explanation 
of Compliance Time'' section in the preamble of the NPRM (78 FR 42895, 
July 18, 2013) should be on the SAR program instead of on widespread 
fatigue damage (WFD). However, Boeing stated that the restrictions 
concerning extensions to compliance times for AD-mandated service 
bulletins related to WFD in the ``Explanation of Compliance Time'' 
section in the preamble of the NPRM might be similar to the SAR 
program.
    We concur that the NPRM (78 FR 42895, July 18, 2013) references to 
``certain programs'' and ``previously established program'' are 
intended to refer to the Model 727 airplane SAR program. However, the 
``Discussion'' section of the NPRM is not restated in this final rule. 
Therefore, no change to this final rule is necessary in this regard.
    We find that clarification is necessary concerning how the SAR 
program and WFD affect this final rule. This final rule is being issued 
to complete actions in one of the service bulletins recommended as a 
part of the Model 727 airplane SAR program, but not previously AD-
mandated. This is necessary because the LOV for Model 727 series 
airplanes is dependent on timely completion of the previously 
established SAR program actions. Since some of those actions, including 
those mandated by this final rule, were not previously mandated, it is 
necessary to mandate them now as a part of defining the service actions 
that support the LOV and preclude WFD. This is the link between WFD and 
the SAR program actions that were not previously mandated by an AD. 
Since the requirements of this final rule support the LOV and preclude 
WFD, the statement that we will not grant any extensions of the 
compliance time to complete any AD-mandated service information related 
to WFD without extensive new data applies to this final rule. We have 
not changed this 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 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 42895, July 18, 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 42895, July 18, 2013).

Costs of Compliance

    We estimate that this AD affects 94 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

Inspection and Modification.........  222 work[dash]hours x            $2,906          $21,776       $2,046,944
                                       $85 per hour = $18,870.
----------------------------------------------------------------------------------------------------------------

    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.
