What to do
Operators of affected Airbus A350-941 and A350-1041 aircraft must amend the applicable Aircraft Flight Manual within 30 days of the directive's effective date to incorporate the specified Temporary Revision 114. Flight crews must be informed of the changes and operate the aircraft according to the updated procedures. Compliance can also be achieved by incorporating a later AFM revision that includes this Temporary Revision.
Summary
EASA Airworthiness Directive 2018-0246 is an airworthiness directive affecting Airbus A350-941 and A350-1041 aeroplanes, excluding those with Airbus modification 113759 embodied in production. This directive addresses an issue with the engine bleed air system related to the Auxiliary Power Unit (APU) bleed leak alert and requires an amendment to the Aircraft Flight Manual (AFM).
What changed
This directive mandates the incorporation of Airbus A350 Aircraft Flight Manual Temporary Revision 114 to update procedures for handling the "AIR APU BLEED LEAK" alert. It does not require installation of the related ECAM Temporary Quick Changes already mandated by a previous AD. The update clarifies operational procedures to prevent repeated engine bleed resets that expose structural parts to heat stress.
Why it matters
The directive is important because repeated resets of the engine 1 bleed system due to false APU bleed leak alerts can expose critical aircraft structures to heat stress, potentially reducing structural integrity. Operators and maintenance teams must follow updated procedures to mitigate this risk and ensure continued airworthiness and safety of affected Airbus A350 aircraft.
