(a) EFFECTIVE DATE This AD is effective June 7, 2018 to all persons except those persons to whom it was made immediately effective by Emergency AD 2018-09-51, issued on April 20, 2018, which contained the requirements of this amendment. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to all CFM International, S.A., (CFM) CFM56-7B20, -7B22, -7B24, -7B26, -7B27, -7B22/B1, -7B24/B1, -7B26/B1, -7B26/B2, -7B27/B1, -7B27/B3, -7B20/3, -7B22/3, -7B24/3, -7B26/3, -7B27/3, -7B22 /3B1, -7B24/3B1, -7B26/3B1, -7B26/3B2, -7B26/3F, -7B26/3B2F, -7B27/3B1 -7B27/3B3, -7B27/3F, -7B27/3B1F, -7B20E, -7B22E, -7B24E, -7B26E, -7B27E, -7B22E/B1, -7B24E/B1, -7B26E/B1, -7B26E/B2, -7B26E/F, -7B26E/ B2F, -7B27E/B1, -7B27E/B3, -7B27E/F, -7B27E/B1F, -7B20/2, -7B22/2, -7B24/2, -7B26/2, -7B27/2, -7B27A, -7B27AE and -7B27A/3 engine models, with 30,000 or more total accumulated flight cycles since new, as of April 20, 2018. (d) SUBJECT Joint Aircraft System Component (JASC) Code 7200, Engine. (e) UNSAFE CONDITION This AD was prompted by a recent event involving an engine failure, resulting in the engine inlet cowl disintegrating, debris penetrating the fuselage causing a loss of pressurization and prompting an emergency descent. There was one passenger fatality as a result of the event. We are issuing this AD to address fan blade failure due to cracking, which could result in an engine in-flight shutdown (IFSD), uncontained release of debris, damage to the engine, damage to the airplane, and possible airplane decompression. (f) COMPLIANCE Comply with this AD within the compliance times specified, unless already done. (g) INSPECTION (1) Within 20 days after the effective date of this AD, perform a one-time ultrasonic inspection of all 24 fan blade dovetail concave and convex sides to detect cracking. (2) Use the Accomplishment Instructions, paragraphs 3.A.(3)(a) through (i) of CFM Service Bulletin (SB) CFM56-7B S/B 72-1033, dated April 20, 2018, to perform the inspection required by paragraph (g)(1) of this AD. (h) CORRECTIVE ACTION If any unserviceable indication, as specified in CFM SB CFM56-7B S/B 72-1033, dated April 20, 2018, is found during any inspection required by this AD, remove the affected fan blade from service before further flight. (i) NO REPORTING REQUIRED Although CFM SB CFM56-7B S/B 72-1033, dated April 20, 2018, specifies to report findings, this AD does not include that requirement. (j) CREDIT FOR PREVIOUS ACTIONS This paragraph provides credit for the actions specified in paragraph (g)(1) of this AD, if those actions were performed before receipt of this AD using CFM SB CFM56-7B S/B 72-1019, dated March 24, 2017; or Revision 1, dated June 13, 2017; or CFM SB CFM56-7B S/B 72-1024, dated July 24, 2017. (k) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS) (1) The Manager, ECO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (l) of this AD. You may email your request to ANE-AD-AMOC@faa.gov. (2) Before using any approved AMOC, notify your appropriate principal in- spector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (3) For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (k)(3)(i) and (k)(3)(ii) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator’s maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, includ- ing substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
