AGENCY:

ACTION:

SUMMARY:
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to CFM International S.A.

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.
DATES:
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.
