[Federal Register Volume 64, Number 199 (Friday, October 15, 1999)] [Rules and Regulations] [Page 55815] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 99-26710] [[Page 55815]] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. 98-ANE-31-AD; Amendment 39-11221; AD 99-15-02] RIN 2120-AA64 Airworthiness Directives; Pratt & Whitney JT9D Series Turbofan Engines; Correction AGENCY: Federal Aviation Administration, DOT. ACTION: Final rule; correction. ----------------------------------------------------------------------- SUMMARY: This document makes a correction to Airworthiness Directive (AD) 99-15-02 applicable to certain Pratt &Whitney (PW) JT9D series turbofan engines that was published in the Federal Register on July 16, 1999 (64 FR 38299). Part number (P/N) and service bulletin (SB) references in the compliance section are incorrect. This document corrects those references. In all other respects, the original document remains the same. EFFECTIVE DATE: October 15, 1999. FOR FURTHER INFORMATION CONTACT: Peter White, Aerospace Engineer, Engine Certification Office, FAA, Engine and Propeller Directorate, 12 New England Executive Park, Burlington, MA 01803-5299; telephone (781) 238-7128, fax (781) 238-7199. SUPPLEMENTARY INFORMATION: A final rule airworthiness directive applicable to Pratt & Whitney (PW) JT9D-3A, -7, -7H, -7A, -7AH, -7F, - 7J, -20, and -20J series turbofan engines, was published in the Federal Register on July 16, 1999 (64 FR 38299). The part number referenced in the AD should read 734514 instead of 734515. After performing the required actions on the flange, P/N 734514, the entire case becomes P/N 734515. Thus, there is no flange with P/N 734715, and the AD must be corrected to eliminate this typographical error. In addition, the Service Bulletin referenced for performing the inspections is changed to refer to the SB that contains the actual inspection procedure. ASB 6343 only refers to ASB 4482. The following correction is needed: Sec. 39.13 [Corrected] 1. On page 38300, in the third column, in the Compliance Section, in paragraph (d), in the fifth line, ``P/N 734515'' is corrected to read ``P/N 734514''. 2. On page 38300, in the third column, in the Compliance Section, in paragraph (d), in the seventh and eighth line, ``PW ASB No. 6343 Revision 1, dated October 8, 1998'' is corrected to read ``PW SB No. 4482, Revision 1, dated July 8, 1976''. 3. On page 38300, in the third column, in the Compliance Section, in paragraph (e), in the second line, ``P/Ns 734515'' is corrected to read ``P/Ns 734514''. Issued in Burlington, Massachusetts, on October 6, 1999. Thomas A. Boudreau, Acting Manager, Engine and Propeller Directorate, Aircraft Certification Service.
