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.
