Discussion

    The FAA issued an NPRM proposing to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) with an AD applicable to certain 
CFM International CFM56-7B turbofan engines. The proposed AD would have 
required a one-time ultrasonic inspection (USI) or eddy current 
inspection (ECI) of certain fan blades and, if they fail the 
inspection, their replacement with parts eligible for installation. The 
proposed action was prompted by a report of an in-flight fan blade 
failure and uncontained forward release of debris on a CFM56-7B 
turbofan engine.
    Since issuing the NPRM, the FAA determined that the identified 
unsafe condition was not adequately addressed by the actions proposed 
in the NPRM. Therefore, the FAA published two final rules, AD 2018-09-
51 (83 FR 23794, May 23, 2018) and AD 2018-10-11 (83 FR 22836, May 17, 
2018) to require initial and repetitive USI or ECI of certain fan 
blades, and to reduce the compliance time for the inspection of certain 
fan blades. The unsafe condition identified in the NPRM is now 
addressed by AD 2018-09-51 (effective June 7, 2018) and AD 2018-10-11 
(effective June 1, 2018).

The Withdrawal

    Accordingly, the FAA withdraws the NPRM (Docket No. FAA-2017-0313, 
Product Identifier 2017-NE-11-AD) published at 82 FR 40516 on August 
25, 2017.
