Compact Series Propellers Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. mstockstill on PROD1PC66 with RULES AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for all Hartzell Propeller Inc. models ( ) HC–( )( )Y( )–( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured ‘‘Y’’ shank aluminum blades. That AD currently requires initial blade inspections, with no repetitive inspections; rework of all ‘‘Y’’ shank aluminum blades including cold rolling of the blade shank retention radius, blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with VerDate Aug<31>2005 18:48 Dec 21, 2007 Jkt 214001 specific models of propellers installed. This AD requires the same actions but clarifies certain areas of the compliance, and updates a certain service bulletin (SB) reference to the most recent SB. This AD results from operators requesting clarification of certain portions of AD 2002–09–08. We are issuing this AD to prevent failure of the propeller blade from fatigue cracks in the blade shank radius, which can result in damage to the airplane and loss of airplane control. DATES: This AD becomes effective January 30, 2008. The Director of the Federal Register previously approved the incorporation by reference of certain publications listed in the regulations as of June 13, 2002 (67 FR 31113, May 9, 2002). The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of January 30, 2008. ADDRESSES: You can get the service information identified in this AD from Hartzell Propeller Inc. Technical Publications Department, One Propeller Place, Piqua, OH 45356; telephone (937) 778–4200; fax (937) 778–4391. 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. FOR FURTHER INFORMATION CONTACT: Tim Smyth, Senior Aerospace Engineer, Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 2300 East Devon Avenue, Des Plaines, IL 60018–4696; e-mail: timothy.smyth@faa.gov; telephone (847) 294–8110; fax (847) 294–7132. SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 by superseding AD 2002–09–08, Amendment 39–12741 (67 FR 31113, May 9, 2002) with a proposed AD. The proposed AD applies to Hartzell Propeller Inc. models ( )HC–( )( )Y ( )–( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured ‘‘Y’’ shank aluminum blades. We published the proposed AD in the Federal Register on August 14, 2006 (71 FR 46413). That action proposed to require the same actions as AD 2002–09–08, but would clarify certain areas of the compliance and would update a certain SB reference to the most recent SB. Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 72915 except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is provided in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment received. Incorporate Service Documents by Reference and Publish Them in the Document Management System The Modification and Replacement Parts Association requests that all service documents deemed essential to the accomplishment of the AD be incorporated by reference into the regulatory instrument, and published in the Docket Management System. We partially agree. We have incorporated pertinent service material into the regulatory section of this AD. However, at this time, the FAA does not post service material on the Federal Docket Management System. We are in the process of reviewing issues surrounding the posting of service bulletins on the Federal Docket Management System as part of an AD docket. Once we have thoroughly examined all aspects of this issue and have made a final determination, we will consider whether our current practice needs to be revised. Format Changes We changed the propeller blade shank cold rolling information from being a note, to paragraphs. We also added paragraphs to the alternative methods of compliance, to make the information more readable. Conclusion We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. Costs of Compliance We estimate that this AD will affect 35,750 propellers installed on airplanes of U.S. registry. We expect this AD will cost about $700 per propeller. Total cost to U.S. operators for this AD would be about $25.025 million. However, we also expect that all of the affected propellers should have already been inspected to comply with the existing AD’s requirements to inspect, and E:\FR\FM\26DER1.SGM 26DER1
