Final rule; correction.
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to CFM International S.A. CFM56-2, CFM56-3, CFM56-5A, CFM56-5B, CFM56-5C, and CFM56-7B series turbofan engines with certain part number (P/N) and serial number (SN) high-pressure compressor (HPC) 4-9 spools installed. In Table 1 of the AD, the HPC 4-9 spool SN GWN05AMO in the 2nd column of the Table is incorrect. This document corrects that error. In all other respects, the original document remains the same.
This final rule is effective February 24, 2012. The effective date for AD 2009-11-02 (74 FR 23305, May 19, 2009) remains June 23, 2009.
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (phone: 800-647-5527) is Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590.

Airworthiness Directive 2009-11-02, Amendment 39-15912 (74 FR 23305, May 19, 2009), currently requires removing certain HPC 4-9 spools listed by P/N and SN in the AD.
As published, in Table 1 of the AD, the HPC 4-9 spool SN GWN05AMO in the 2nd column of the Table is incorrect.
No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register.
The effective date of this AD remains June 23, 2009.
