[FR Doc. 2013–05587 Filed 3–19–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1031; Directorate Identifier 2012–NE–31–AD; Amendment 39– 17391; AD 2013–05–19] RIN 2120–AA64 Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611–8 turbofan engines. This AD requires inspection and replacement, if necessary, of affected bolts. This AD was prompted by a quality review determination that bolts with reduced material properties may have been installed in some engines. We are issuing this AD to prevent uncontained turbine disc fracture and damage to the airplane. DATES: This AD becomes effective April 24, 2013. ADDRESSES: The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001. FOR FURTHER INFORMATION CONTACT: Frederick Zink, Aerospace Engineer, Engine Certification Office, FAA, Engine & Propeller Directorate, 12 New England Executive Park, Burlington, MA 01803; email: frederick.zink@faa.gov; telephone: 781–238–7779; fax: 781– 238–7199. 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 was published in the Federal Register on November 13, 2012 (77 FR 67582). That NPRM proposed to correct an unsafe condition for the specified PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 17075 products. The Mandatory Continuing Airworthiness Information states: The results of a recent quality review of low pressure turbine (LPT) stage 1 static air seal and high pressure turbine (HPT) stage 1 air seal support bolts identified that, before installation, those bolts may have not been inspected. As a consequence, bolts with reduced material properties may have been installed in some engines. This condition, if not detected and corrected, could lead to failure of a bolt, potentially causing turbine disc fracture and release of high-energy debris, possibly resulting in damage to the aeroplane and/or injury to the occupants. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 67582, November 13, 2012). However, we changed paragraph (e) of this AD by removing the reporting requirement because that requirement is not necessary to correct the unsafe condition. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed (77 FR 67582, November 13, 2012). Costs of Compliance Based on the service information, we estimate that this AD affects about 20 engines of U.S. registry. We also estimate that it will take about 4 hours per product to comply with this AD. The average labor rate is $85 per hour. Required parts will cost about $1,848 per engine. Based on these figures, we estimate the cost of the AD on U.S. operators to be $43,760. 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 E:\FR\FM\20MRR1.SGM 20MRR1 17076 Federal Register / Vol. 78, No. 54 / Wednesday, March 20, 2013 / Rules and Regulations 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 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 to the extent that it justifies making a regulatory distinction, 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (phone: (800) 647–5527) is provided in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8 turbofan engines. 
This AD requires inspection and replacement, if necessary, of affected 
bolts. This AD was prompted by a quality review determination that 
bolts with reduced material properties may have been installed in some 
engines. We are issuing this AD to prevent uncontained turbine disc 
fracture and damage to the airplane.

DATES: This AD becomes effective April 24, 2013.

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 was published in the Federal Register on November 13, 2012 
(77 FR 67582). That NPRM proposed to correct an unsafe condition for 
the specified products. The Mandatory Continuing Airworthiness 
Information states:

    The results of a recent quality review of low pressure turbine 
(LPT) stage 1 static air seal and high pressure turbine (HPT) stage 
1 air seal support bolts identified that, before installation, those 
bolts may have not been inspected. As a consequence, bolts with 
reduced material properties may have been installed in some engines.
    This condition, if not detected and corrected, could lead to 
failure of a bolt, potentially causing turbine disc fracture and 
release of high-energy debris, possibly resulting in damage to the 
aeroplane and/or injury to the occupants.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 67582, November 13, 
2012). However, we changed paragraph (e) of this AD by removing the 
reporting requirement because that requirement is not necessary to 
correct the unsafe condition.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed (77 FR 67582, 
November 13, 2012).

Costs of Compliance

    Based on the service information, we estimate that this AD affects 
about 20 engines of U.S. registry. We also estimate that it will take 
about 4 hours per product to comply with this AD. The average labor 
rate is $85 per hour. Required parts will cost about $1,848 per engine. 
Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $43,760.

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

[[Page 17076]]

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 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 to the extent that 
it justifies making a regulatory distinction, 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (phone: (800) 647-5527) is provided in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
