SUPPLEMENTARY INFORMATION: RIN 2120–AA64 Discussion Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop 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 March 21, 2014 (79 FR 15707). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: If before the effective date of this AD you removed from an engine any EEC that had EEC software standard A14 or earlier and your engine no longer has an EEC with software standard A14 or earlier, you have met the requirements of this AD. VerDate Mar<15>2010 Federal Aviation Administration FOR FURTHER INFORMATION CONTACT: We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. This AD requires removal of the O-ring seal from the fuel manifold fitting. This AD was prompted by reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. We are issuing this AD to prevent in-flight fuel leakage, which could lead to engine fire, damage to the engine, and damage to the airplane. DATES: This AD becomes effective August 15, 2014.

SUMMARY: 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– 1059; or in person at the Docket Management Facility 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 address for the Docket Office (phone: 800–647–5527) is Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 There have been reported incidences of fuel leaks at the interface between the flexible fuel manifold and the fuel nozzle. On occasion, these events resulted in an engine fire on PW100 series engine installations. The data indicates that nearly all of the subject manifold fuel leaks were caused by inadequate B-nut torque application during installation, after maintenance work was performed on the fuel nozzle/manifold. Sealing of the fitting connections between the fuel manifolds and the fuel nozzle adapters is achieved through conical metalto-metal surface seating. An additional O-ring seal on the fitting was installed to arrest any fuel leak past the conical sealing surfaces. Inservice experience has indicated that leakage past the sealing surfaces, as a result of improper torquing during installation of the manifold, may not be immediately evident until the failure of the O-ring seal allows the fuel to leak into the nacelle area. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Request To Mandate Incorporation of Service Bulletins UTair Aviation JSC requested that we mandate incorporation of P&WC Service Bulletins (SBs) PW100–72–21841, Revision No. 1, dated November 29, 2013; and PW100–72–21848, Revision No. 1, dated November 15, 2013, in the AD. The commenter suggested that incorporation by reference of these SBs would improve safety compared to the compliance proposed in the NPRM (79 FR 15707, March 21, 2014). We disagree. We note that prior to implementation of these SBs, an operator would need to remove the affected O-ring seals, which would fulfill the requirements of this AD. We do not find that requiring accomplishing these service bulletins through incorporation by reference in this AD is necessary. We did not change this AD. E:\FR\FM\11JYR1.SGM 11JYR1 Federal Register / Vol. 79, No. 133 / Friday, July 11, 2014 / Rules and Regulations 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 affects about 150 engines installed on airplanes of U.S. registry. We also estimate that it would take about 2.5 hours per engine to perform the inspection or replacement required by this AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $31,875. tkelley on DSK3SPTVN1PROD 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. 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.

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 March 21, 2014 (79 FR 
15707). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    There have been reported incidences of fuel leaks at the 
interface between the flexible fuel manifold and the fuel nozzle. On 
occasion, these events resulted in an engine fire on PW100 series 
engine installations. The data indicates that nearly all of the 
subject manifold fuel leaks were caused by inadequate B-nut torque 
application during installation, after maintenance work was 
performed on the fuel nozzle/manifold.
    Sealing of the fitting connections between the fuel manifolds 
and the fuel nozzle adapters is achieved through conical metal-to-
metal surface seating. An additional O-ring seal on the fitting was 
installed to arrest any fuel leak past the conical sealing surfaces. 
In-service experience has indicated that leakage past the sealing 
surfaces, as a result of improper torquing during installation of 
the manifold, may not be immediately evident until the failure of 
the O-ring seal allows the fuel to leak into the nacelle area.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Mandate Incorporation of Service Bulletins

    UTair Aviation JSC requested that we mandate incorporation of P&WC 
Service Bulletins (SBs) PW100-72-21841, Revision No. 1, dated November 
29, 2013; and PW100-72-21848, Revision No. 1, dated November 15, 2013, 
in the AD. The commenter suggested that incorporation by reference of 
these SBs would improve safety compared to the compliance proposed in 
the NPRM (79 FR 15707, March 21, 2014).
    We disagree. We note that prior to implementation of these SBs, an 
operator would need to remove the affected O-ring seals, which would 
fulfill the requirements of this AD. We do not find that requiring 
accomplishing these service bulletins through incorporation by 
reference in this AD is necessary. We did not change this AD.

[[Page 39959]]

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 affects about 150 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 
2.5 hours per engine to perform the inspection or replacement required 
by this AD. The average labor rate is $85 per hour. Based on these 
figures, we estimate the cost of this AD on U.S. operators to be 
$31,875.

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.
