## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2018-26-01, which applies to all CFM International, S.A. (CFM) Model CFM56-7B engines. AD 2018-26-01 requires initial and repetitive ultrasonic inspections or eddy current inspections of certain fan blades for crack indications and, depending on the results of the inspections, replacement with parts eligible for installation. Since the FAA issued AD 2018-26-01, CFM issued updated service material providing improvements to the ultrasonic inspection procedures and expanding the inspection area. This proposed AD would require initial and repetitive ultrasonic inspections or eddy current inspections of certain fan blades for crack indications and, depending on the results of the inspections, replacement with parts eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
