| 96-32435 | Airworthiness Directives; CFM International Model CFM56-3C-1 and CFM56-3B-2 Turbofan Engines | Rule | This amendment supersedes an existing airworthiness directive (AD), applicable to all CFM International (CFMI) CFM56-3C-1 and certain CFM56-3B-2 engines, that currently requires the removal from service of certain fan disk and fan blade hardware, and limits the use of CFM56- 3C-1 thrust levels. This amendment requires removal of additional fan blade hardware, requires an Airplane Flight Manual (AFM) revision to impose thrust level limitations for airplanes equipped with affected engines, and requires the installation of redesigned fan blades as a terminating action to the thrust level limitations of this AD. The existing AD requirements for certain CFM56-3B-2 engines are unchanged and carried over into this final rule AD. This amendment is prompted by the availability of redesigned fan blades that are not subject to the thrust level limitations, and the need to clarify the AD requirements by deleting references to specific AFMs. The actions specified by this AD are intended to prevent a fan blade failure that can result in complete loss of engine power. | 1996-12-30 | 1996 | 12 | https://www.federalregister.gov/documents/1996/12/30/96-32435/airworthiness-directives-cfm-international-model-cfm56-3c-1-and-cfm56-3b-2-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-1996-12-30/pdf/96-32435.pdf | Transportation Department | 492 | This amendment supersedes an existing airworthiness directive (AD), applicable to all CFM International (CFMI) CFM56-3C-1 and certain CFM56-3B-2 engines, that currently requires the removal from service of certain fan disk and fan blade hardware, and... |
