[Federal Register Volume 62, Number 74 (Thursday, April 17, 1997)] [Proposed Rules] [Page 18726] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 97-9882] ======================================================================== Proposed Rules Federal Register ________________________________________________________________________ This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. ======================================================================== Federal Register / Vol. 62, No. 74 / Thursday, April 17, 1997 / Proposed Rules [[Page 18726]] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. 86-ANE-13] RIN 2120-AA64 Airworthiness Directives; CFM International CFM56-3 and -3B Series Turbofan Engines AGENCY: Federal Aviation Administration, DOT. ACTION: Proposed rule; withdrawal. ----------------------------------------------------------------------- SUMMARY: This action withdraws a notice of proposed rulemaking that would have added a new airworthiness directive (AD), applicable to CFM International (CFMI) CFM56-3 and -3B series turbofan engines. That action proposed to amend an existing AD and would have required the installation of a riveted oil distributor, Part Number (P/N) 335-305- 804-0. Since the issuance of the NPRM, the manufacturer has advised the Federal Aviation Administration (FAA) that the entire CFM56-3 and -3B fleet has been retrofitted with the new riveted oil distributor, P/N 335-305-804-0, and that there are no oil distributors, P/N 335-305-800- 0, presently in service. The FAA has therefore reviewed its position, and has concluded that the proposed actions are unnecessary. Accordingly, the proposed rule is withdrawn. FOR FURTHER INFORMATION CONTACT: Glorianne Messemer, Aerospace Engineer, Engine Certification Office, FAA, Engine and Propeller Directorate, 12 New England Executive Park, Burlington, MA 01803-5299; telephone (617) 238-7132, fax (617) 238-7199. SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to supersede an airworthiness directive (AD), applicable to CFM International (CFMI) CFM56-3 and -3B engines, was published in the Federal Register on December 2, 1986 (51 FR 43383). The proposed rule would have amended the existing AD that requires initial and repetitive inspections of the transfer gearbox for radial driveshaft oil distributor looseness and condition of the spirolock. The proposed rule would have required a riveted oil distributor, Part Number (P/N) 335-305-804-0, to be installed in accordance with CFMI CFM56-3/-3B Service Bulletin No. 72-253, dated June 27, 1986, as a terminating action to the repetitive inspection program. Since the issuance of the NPRM, the manufacturer has advised the Federal Aviation Administration (FAA) that the entire CFM56-3 and -3B fleet has been retrofitted with the new riveted oil distributor, P/N 335-305-804-0, and that there are no oil distributors, P/N 335-305-800- 0, presently in service, nor does the manufacturer plan to introduce any into service in the future. The installation of the riveted oil distributor provides a permanent fix for oil distributor looseness and eliminates the need for repetitive inspections. The FAA has therefore reviewed its position, and has concluded that the proposed actions are unnecessary. Accordingly, the proposed rule is hereby withdrawn. Withdrawal of this final rule constitutes only such action, and does not preclude the agency from issuing another notice in the future, nor does it commit the agency to any course of action in the future. Since this action only withdraws a notice of proposed rulemaking, it is neither a proposed nor a final rule and therefore, is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Withdrawal Accordingly, the Notice of Proposed Rulemaking, Docket 86-ANE-13, published in the Federal Register on December 2, 1986 (51 FR 43383), is withdrawn. Issued in Burlington, Massachusetts, on April 8, 1997. Jay J. Pardee, Manager, Engine and Propeller Directorate, Aircraft Certification Service.
