Airworthiness Directive · Amendment 39-14082 · CFM International CFM56-5, -5B, and -5C Series Turbofan Engines
CFM International CFM56-5, -5B, and -5C Series Turbofan Engines
This AD applies to CFM International CFM56-5, -5B, and -5C series turbofan engines with air turbine starters, part numbers (P/Ns) VIN 3505582-24 (301-807-004-0), VIN 3505582-25 (301-807-005-0), VIN 3505582-40 (301-781-203-0), VIN 3505582-41 (301-806-602-0), VIN 3505582-42 (301-806-802-0), VIN 3505582-60 (301-790-903-0), VIN 3505582-61 (301-806-702-0), and VIN 3505582-62 (301-806-902-0), installed. These engines are installed on, but not limited to, Airbus A319, A320, A321, and A340 airplanes.
The FAA is adopting a new airworthiness directive (AD) for CFM International CFM56-5, -5B, and -5C series turbofan engines. This AD requires removing certain part number (P/N) air turbine starters from service. This AD results from several reports of uncontained failures of air turbine starters where high-energy particles were not contained within the containment feature of the starter. We are issuing this AD to prevent uncontained failures of air turbine starters, which could result in damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
At the next air turbine starter shop visit, but no later than December 31, 2009, remove any air turbine starter, that has a P/N specified in this AD, from service.
After the effective date of this AD, do not install any air turbine starters that have a P/N specified in this AD into any engine.
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.
