Airplanes Discussion Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC–7–1 and DHC–7–100 airplanes. This AD was prompted by reports of cracks that were discovered in the outboard nacelles upper longeron channels and angles. This AD requires a one-time detailed visual inspection for cracking in the outboard nacelles upper longeron channels and angles; and repair if necessary. We are issuing this AD to detect and correct cracks in the outboard nacelles upper longeron channels and angles, which could lead to the loss of stiffness in the forward engine mount; and possible catastrophic failure. DATES: This AD becomes effective November 10, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 10, 2015.

Jkt 238001 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC–7–1 and DHC–7–100 airplanes. The NPRM published in the Federal Register on April 13, 2015 (80 FR 19572). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–34, dated October 2, 2014, dated (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC–7–1 and DHC–7–100 airplanes. The MCAI states: Longitudinal cracks were discovered in the outboard nacelles upper longeron channels and angles at station XN1 78. The cracks were partially hidden by bearing blocks, Part Number (P/N) 75420978, at the nacelle latch locations. Undetected, these cracks may lead to the loss of stiffness in the forward engine mount; which may lead to a catastrophic failure. Required actions include a one-time detailed visual inspection for cracking of the outboard nacelles upper longeron channels and angles. Corrective actions include repair, if necessary. You may PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2015-06840002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 19572, April 13, 2015) or on the determination of the cost to the public. Conclusion We reviewed the relevant data 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 (80 FR 19572, April 13, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 19572, April 13, 2015). Related Service Information Under 1 CFR Part 51 Viking Air Limited has issued Service Bulletin V7–54–02, Revision NC, dated December 14, 2012. The service information describes procedures for an inspection for cracks in the outboard nacelles upper longeron channels and angles; and repair if necessary. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this AD. Costs of Compliance We estimate that this AD affects 10 airplanes of U.S. registry. We also estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $2,550, or $255 per product. 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. E:\FR\FM\06OCR1.SGM 06OCR1 Federal Register / Vol. 80, No. 193 / Tuesday, October 6, 2015 / Rules and Regulations 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 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 the 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.

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. 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 the 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 makes the necessary updates for airspace areas within the National Airspace System. History Federal Aviation Administration Airspace Order 7400.9, Airspace Designations and Reporting Points, incorporated by reference in 14 CFR 71.1, is published yearly. Amendments referred to as ‘‘effective date straddling amendments’’ were published under Order 7400.9Y (dated August 6, 2014, and effective September 15, 2014), but became effective under Order 7400.9Z (dated August 6, 2015, and effective September 15, 2015). This action incorporates these rules into the current FAA Order 7400.9Z. Accordingly, as this is an administrative correction to update final rule amendments into FAA Order 7400.9Z, notice and public procedure under 5 U.S.C. 553(b) are unnecessary. Also, to bring these rules and legal descriptions current, I find that good cause exists, under 5 U.S.C. 553(d), for making this amendment effective in less than 30 days. Availability and Summary of Documents for Incorporation by Reference This document amends FAA Order 7400.9Z, Airspace Designations and Reporting Points, dated August 6, 2015, and effective September 15, 2015. FAA Order 7400.9Z is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.9Z lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. The Rule This action amends title 14 Code of Federal Regulations (14 CFR) Part 71 to incorporate certain final rules into the current FAA Order 7400.9Z, Airspace PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Designations and Reporting Points, dated August 6, 2015, and effective September 15, 2015, which are depicted on aeronautical charts. Regulatory Notices and Analyses The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (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 that 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. List of Subjects in 14 CFR Part 71 Airspace, Incorporation by reference, Navigation (air). Adoption of the Amendment In consideration of the foregoing, the Federal Aviation Administration 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.

Airworthiness Directives; Viking Air Limited (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Viking Air Limited (Type Certificate Previously Held by Bombardier, 
Inc.) Model DHC-7-1 and DHC-7-100 airplanes. This AD was prompted by 
reports of cracks that were discovered in the outboard nacelles upper 
longeron channels and angles. This AD requires a one-time detailed 
visual inspection for cracking in the outboard nacelles upper longeron 
channels and angles; and repair if necessary. We are issuing this AD to 
detect and correct cracks in the outboard nacelles upper longeron 
channels and angles, which could lead to the loss of stiffness in the 
forward engine mount; and possible catastrophic failure.

DATES: This AD becomes effective November 10, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 10, 
2015.

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 all Viking Air Limited 
(Type Certificate Previously Held by Bombardier, Inc.) Model DHC-7-1 
and DHC-7-100 airplanes. The NPRM published in the Federal Register on 
April 13, 2015 (80 FR 19572).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-34, dated October 2, 2014, dated (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Viking Air Limited (Type 
Certificate Previously Held by Bombardier, Inc.) Model DHC-7-1 and DHC-
7-100 airplanes. The MCAI states:

    Longitudinal cracks were discovered in the outboard nacelles 
upper longeron channels and angles at station XN1 78. The cracks 
were partially hidden by bearing blocks, Part Number (P/N) 75420978, 
at the nacelle latch locations. Undetected, these cracks may lead to 
the loss of stiffness in the forward engine mount; which may lead to 
a catastrophic failure.

    Required actions include a one-time detailed visual inspection for 
cracking of the outboard nacelles upper longeron channels and angles. 
Corrective actions include repair, if necessary. You may examine the 
MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0684-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 19572, April 13, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data 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 (80 FR 19572, April 13, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 19572, April 13, 2015).

Related Service Information Under 1 CFR Part 51

    Viking Air Limited has issued Service Bulletin V7-54-02, Revision 
NC, dated December 14, 2012. The service information describes 
procedures for an inspection for cracks in the outboard nacelles upper 
longeron channels and angles; and repair if necessary. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section of this AD.

Costs of Compliance

    We estimate that this AD affects 10 airplanes of U.S. registry.
    We also estimate that it will take about 3 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $2,550, or $255 per product.
    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.

[[Page 60285]]

    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 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 the 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
