ACTION: Final rule. pwalker on PROD1PC71 with RULES AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT9D series turbofan engines. That AD currently requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer’s Instructions for Continued Airworthiness (ICA) to VerDate Aug<31>2005 18:23 Mar 07, 2007 Jkt 211001 include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. This AD modifies the JT9D series engines ALS sections of the manufacturer’s manuals and an air carrier’s approved continuous airworthiness maintenance program to incorporate additional inspection requirements. This AD results from the need to require enhanced inspection of selected critical life-limited parts of JT9D series turbofan engines. We are issuing this AD to prevent critical lifelimited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane. DATES: This AD becomes effective April 12, 2007. ADDRESSES: You may examine the AD docket on the Internet at http:// dms.dot.gov or in Room PL–401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC. FOR FURTHER INFORMATION CONTACT: Mark Riley, Aerospace Engineer, Engine Certification Office, FAA, Engine and Propeller Directorate, 12 New England Executive Park, Burlington, MA 01803– 5299; telephone (781) 238–7758, fax (781) 238–7199. SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to PW JT9D series turbofan engines. We published the proposed AD in the Federal Register on November 2, 2005 (70 FR 66300). That action proposed to modify the JT9D series engines ALS sections of the manufacturer’s manuals and an air carrier’s approved continuous airworthiness maintenance program to incorporate additional inspection requirements. PW has added mandatory eddy current inspections (ECIs) for the web cooling holes in high pressure turbine (HPT) stage 1 disks installed in engine models JT9D–7R4D, –7R4D1, –7R4E, and –7R4E1, and for web tie-rod holes in HPT stage 2 disks installed in JT9D–3A, –7, –7A, –7H, –7AH, –7F, –7J, –20, and –20J engines. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. Examining the AD Docket You may examine the docket that contains the AD, any comments received, and any final disposition in person at the Docket Management Facility Docket Office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647–5227) is located on the plaza level of the PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Department of Transportation Nassif Building at the street address stated in ADDRESSES. Comments will be available in the AD docket shortly after the DMS receives them. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Delete ECIs for JT9D–59A, –70A, –7Q, and –7Q3 Engines One commenter, Japan Airlines, requests that we delete the ECIs for JT9D–59A, –70A, –7Q, and –7Q3 engines from the table in the proposed AD compliance section. The commenter points out that the proposed AD preamble paragraph entitled ‘‘FAA’s Determination and Requirements of the Proposed AD’’ does not include ECIs for JT9D–59A, –70A, –7Q, and –7Q3 engines. We do not agree. We inadvertently omitted listing the requirement of ECI of the HPT stage 1 disk web cooling holes on JT9D–59A, –70A, –7Q, and –7Q3 engines, under the proposed AD preamble paragraph entitled ‘‘FAA’s Determination and Requirements of the Proposed AD’’. The proposed AD compliance section and the compliance section in this AD, correctly list those engine models. We did not change the AD. Request To Wait To Issue the AD Japan Airlines requests that we wait to issue the AD until Pratt & Whitney provides the ECI procedure to the operators. The commenter states that the JT9D–7 Engine Manual Section 72–51– 02, Inspection 05, has not been published yet. We do not agree. Although the ECI procedure was not published in the JT9D–7 Engine Manual as of December 26, 2005 when the comment was sent, it was incorporated into the JT9D–7 Engine Manual on February 15, 2006. We do not need to wait to issue the AD. Request To Revise Engine Manual Japan Airlines requests that we recommend to Pratt & Whitney to revise the JT9D engine manual to remove the specific manufacturer’s name of the ECI equipment required to perform ECIs, and to only list the technical specifications required to perform the ECIs. The commenter states that operators may not own the ECI equipment specified in the Pratt & Whitney JT9D engine manual, but may have similar equipment capable of performing the inspections.
