S.A. that isolated a production batch of fan blades with nonconforming geometry of mid-span shroud tips of the fan blades. This defect could cause the upper panel of the fan blade to be liberated following foreign object damage (FOD) or a bird strike, and likely result in an inflight shutdown (IFSD). We are issuing this AD to prevent an IFSD of one or more engines following FOD or a bird strike. (e) Compliance Comply with this AD within the compliance times specified, unless already done. (f) Remove Fan Blades From Service For engines that have fan blades, P/N 338-002-114-0, with S/Ns listed in Appendix A of CFM International SB No. CFM56-5B S/B 72- 0777, Revision 1, dated April 11, 2011, remove the fan blades from service within 5,000 flight hours after the effective date of this AD.
