This amendment adopts a new airworthiness directive (AD), applicable to CFM International CFM56-5 series turbofan engines, that requires rework of the air turbine engine starter. This amendment is prompted by three reports of air turbine engine starter failures. The actions specified by this AD are intended to prevent an air turbine engine starter failure, which could result in damage to the engine electrical harnesses.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
