[Docket No. FAA–2013–0342; Directorate Identifier 2013–NE–14–AD; Amendment 39– 17750; AD 2014–03–16] SUPPLEMENTARY INFORMATION: RIN 2120–AA64 Discussion Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co. KG Turbofan Engines 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 was published in the Federal Register on September 26, 2013 (78 FR 59291). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co. KG (RRD) Tay 620–15, 650–15, and 651–54 turbofan engines. This AD requires replacement of low-pressure compressor (LPC) fan blades. This AD was prompted by the discovery that the LPC fan blades leading edges erode in service and create an unacceptable blade flutter margin. We are issuing this AD to prevent LPC fan blade failure, damage to the engine, and damage to the airplane. DATES: This AD becomes effective March 18, 2014. 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. SUMMARY: ehiers on DSK2VPTVN1PROD with RULES Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2013– 0342; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except VerDate Mar<15>2010 13:33 Feb 10, 2014 Jkt 232001 Service history of Tay series engines discovered that low pressure compressor (LPC) fan blade leading edge is exposed to excessive deterioration. The LPC fan blade leading edge profile influences the LPC aerodynamic characteristics and stability. This condition, if not corrected, could reduce fan flutter margin and, in some cases, could lead to fan blade failure, possibly resulting in uncontained release of high energy debris with consequent damage to, and/or reduced control of, the aeroplane. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/ #!documentDetail;D=FAA-2013-03420002. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. The commenter supports the NPRM (78 FR 59291, September 26, 2013). Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed. PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 Costs of Compliance We estimate that this AD will affect about 52 engines of U.S. registry. We also estimate that it will take about six hours per product to comply with this AD. The average labor rate is $85 per hour. Required parts will cost about $11,000 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $598,520. 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 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.

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co. KG 
Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Rolls-Royce Deutschland Ltd & Co. KG (RRD) Tay 620-15, 650-15, and 651-
54 turbofan engines. This AD requires replacement of low-pressure 
compressor (LPC) fan blades. This AD was prompted by the discovery that 
the LPC fan blades leading edges erode in service and create an 
unacceptable blade flutter margin. We are issuing this AD to prevent 
LPC fan blade failure, damage to the engine, and damage to the 
airplane.

DATES: This AD becomes effective March 18, 2014.

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.

    You may examine the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2013-
0342; 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 mandatory continuing airworthiness information 
(MCAI), 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

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 was published in the Federal Register on September 26, 2013 (78 FR 
59291). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Service history of Tay series engines discovered that low 
pressure compressor (LPC) fan blade leading edge is exposed to 
excessive deterioration. The LPC fan blade leading edge profile 
influences the LPC aerodynamic characteristics and stability. This 
condition, if not corrected, could reduce fan flutter margin and, in 
some cases, could lead to fan blade failure, possibly resulting in 
uncontained release of high energy debris with consequent damage to, 
and/or reduced control of, the aeroplane.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0342-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The commenter supports the 
NPRM (78 FR 59291, September 26, 2013).

Conclusion

    We reviewed the available data, including 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 will affect about 52 engines of U.S. 
registry. We also estimate that it will take about six hours per 
product to comply with this AD. The average labor rate is $85 per hour. 
Required parts will cost about $11,000 per engine. Based on these 
figures, we estimate the cost of this AD on U.S. operators to be 
$598,520.

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

    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.

[[Page 8082]]

    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
