[Federal Register Volume 80, Number 105 (Tuesday, June 2, 2015)] [Proposed Rules] [Pages 31325-31326] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-12768] [[Page 31325]] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2013-1059; Directorate Identifier 2013-NE-36-AD] RIN 2120-AA64 Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2014-14- 02, which applies to certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 requires removal of the O-ring seal from the fuel manifold fitting. Since we issued AD 2014-14-02, we received reports of fuel seepage past the metal-to-metal sealing surfaces of the fuel nozzle and fuel manifold flow adapter. This proposed AD would require replacement of the fuel nozzle and the fuel manifold flow adapter. We are proposing this AD to prevent in-flight fuel leakage, engine fire, damage to the engine, and damage to the airplane. DATES: We must receive comments on this proposed AD by August 3, 2015. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2013-1059; Directorate Identifier 2013-NE-36-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On June 30, 2014, we issued AD 2014-14-02, Amendment 39-17896 (79 FR 39958, July 11, 2014), (``AD 2014-14-02''), for certain P&WC PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 requires removal of the O-ring seal from the fuel manifold fitting. AD 2014-14-02 resulted from reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. We issued AD 2014-14-02 to prevent in-flight fuel leakage, engine fire, damage to the engine, and damage to the airplane. Actions Since AD 2014-14-02 Was Issued Since we issued AD 2014-14-02, we have received reports of fuel seepage past the metal to metal sealing surfaces of the fuel nozzle and fuel manifold flow adapter. The manufacturer has since redesigned the fuel manifold flow adapter to prevent in-flight fuel leakage. This redesign incorporates new internal diameters on the fuel manifold adapters and the fuel nozzles. Related Service Information Under 1 CFR Part 51 We reviewed P&WC SB No. PW100-72-21861, dated November 21, 2014, which identifies the final fuel nozzle configuration. 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 NPRM. Other Related Service Information P&WC SB No. PW100-72-21861, dated November 21, 2014, refers to the following additional SBs that provide the final fuel nozzle configuration: P&WC SB No. PW100-72-21803, Revision No. 5, dated November 21, 2014, P&WC SB No. PW100-72-21860, Revision No. 2, dated November 21, 2014, and P&WC SB No. PW100-72-21841, Revision No. 3, dated December 22, 2014. This service information is available by the means identified in the ADDRESSES section of this NPRM. FAA's Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require replacement of the fuel nozzle and the fuel manifold flow adapter. Costs of Compliance We estimate that this proposed AD would affect 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 replacement required by this proposed AD. The average labor rate is $85 per hour. The cost of a fuel nozzle manifold replacement is $146,594. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $22,020,975. [[Page 31326]] 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 have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2014-14-02, Amendment 39-17896 (79 FR 39958, July 11, 2014), and adding the following new AD: Pratt & Whitney Canada Corp.: Docket No. FAA-2013-1059; Directorate Identifier 2013-NE-36-AD.
