Airworthiness Directive · Amendment 39-12461 · CFM International, S.A. CFM56-5 Series Turbofan Engines
CFM International, S.A. CFM56-5 Series Turbofan Engines
This airworthiness directive (AD) is applicable to CFM International, S.A. CFM56-5 series turbofan engines with Honeywell Engines & Systems air turbine engine starters, part numbers (P/N's) 3505582-2, 3505582-3, 3505582-4, 3505582-12, 3505582-14, 3505582-15, 3505582-22, and 3505582-23 installed. These engines are installed on, but not limited to Airbus Industries A318, A319, A320, A321 and A340 airplanes.
This amendment adopts a new airworthiness directive (AD), that is applicable to CFM International, S.A. (CFMI) CFM56-5 series turbofan engines. This amendment requires replacement of the magnetic drain plug on certain part number (P/N) air turbine engine starters manufactured by Honeywell Engines & Systems. This amendment is prompted by three instances of uncontained air turbine engine starter failures, resulting in cowl damage. The actions specified by this AD are intended to prevent uncontained failure of the starter and possible damage to the airplane.
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.
