SUPPLEMENTARY INFORMATION:

On November 30, 2009 (74 FR 62481), we published a final rule AD, FR Doc. E9-28236, in the Federal Register. That AD applies to GE CF34-1A, CF34-3A, and CF34-3B series turbofan engines. We are delaying the effective date to allow us a sufficient amount of time to make corrections to the compliance text of the final rule. Since AD 2009-24-11 was issued, we discovered that when we recodified the compliance section as part of our response to a comment received on the proposed AD, we inadvertently left out of the AD certain fan blade effectivity information from paragraphs (f) and (g) and (j). Paragraphs (f) and (g) are missing information on fan blades, P/Ns 6018T30P14 or 4923T56G08, that have any fan blade S/Ns listed in Appendix A of General Electric Aircraft Engines (GEAE) Service Bulletin (SB) No. CF34-AL S/B 72-0245, Revision 01, dated July 30, 2008. Also, paragraph (j) is missing Start Printed Page 69260information on fan blades, P/N 6018T30P14 or P/N 4923T56G08, that have any fan blade S/Ns listed in Appendix A of GEAE SB No. CF34-BJ S/B 72-0229, Revision 01, dated July 30, 2008.
