Turbofan Engines Modified by Supplemental Type Certificate SE00034EN AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are superseding airworthiness directive (AD) 2013-02-02 for certain CFM International, S.A. CFM56-3, CFM56-3B, and CFM56-3C turbofan engines. AD 2013-02-02 required removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. This AD corrects the serial numbers (S/Ns) listed in AD 2013-02-02. This AD was prompted by reports that certain HPT disk S/Ns in AD 2013- 02-02 and in certain Pratt & Whitney service information are incorrect. We are issuing this AD to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane. DATES: This AD is effective August 9, 2016. The Director of the Federal Register approved the incorporation by reference [[Page 48322]] of a certain publication listed in this AD as of August 9, 2016.

SUPPLEMENTARY INFORMATION: Discussion On January 14, 2013, we issued AD 2013-02-02, Amendment 39-17323 (78 FR 5712, January 28, 2013), (``AD 2013-02-02'') for all CFM56-3, CFM56-3B, and CFM56-3C turbofan engines modified by Supplemental Type Certificate SE00034EN, with certain HPT disks, installed. AD 2013-02-02 required removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. AD 2013-02-02 resulted from a report of a forging process error during manufacture of these HPT disks. We issued AD 2013-02-02 to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane. Actions Since AD 2013-02-02 Was Issued Since we issued AD 2013-02-02, we received reports that certain HPT disk S/Ns GLKBAA9307, GLKBAA9335, GLKBAA9404, GLKBAA9407, and GLKBAA9409, in AD 2013-02-02 and in certain Pratt & Whitney service information are incorrect. The correct S/Ns are: GKLBAA9307, GKLBAA9335, GKLBAA9404, GKLBAA9407, and GKLBAA9409. Related Service Information Under 1 CFR Part 51 We reviewed Pratt & Whitney Corp. Special Instruction No. 6F-12, Revision A, dated May 17, 2016. The Special Instruction describes procedures for reducing the maximum life limit for affected HPT disks. 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. FAA's Determination We are issuing 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. AD Requirements This AD requires removal from service of affected HPT disks at certain recalculated reduced maximum life limits. FAA's Justification and Determination of the Effective Date No domestic operators use this product. Therefore, we find that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2012-1289; Directorate Identifier 2012-NE-43-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this 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 AD. Costs of Compliance We estimate that this AD affects 0 engines installed on airplanes of U.S. registry. We also estimate that it will take about 61 hours per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $0 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $0. 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 This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on [[Page 48323]] 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 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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (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) 2013-02-02, Amendment 39-17323 (78 FR 5712, January 28, 2013), (``AD 2013-02-02''), and adding the following new AD: 2016-14-10 CFM International, S.A. Turbofan Engines Modified by Supplemental Type Certificate SE00034EN: Amendment 39-18591; Docket No. FAA-2012-1289; Directorate Identifier 2012-NE-43-AD.
