Airworthiness Directives; Airbus Airplanes

FAA / Federal Register · 2020-23280

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes. This AD was prompted by a report that during a certification exercise, it was identified that there was a risk of an engine bleed system over- temperature, without the engine bleed valve closing; the associated engine bleed valve should automatically close. This AD requires revising the existing airplane flight manual (AFM) to incorporate procedures to be applied if an engine bleed over-temperature occurs when the associated engine bleed valve is jammed open, and provides for the optional embodiment of updated flight warning computer (FWC) software, which would terminate the AFM revision, as specified in a European Union Aviation Safety Agency (EASA), which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
