Airworthiness Directive · Amendment 39-19534 · Pneumatic
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category, as identified in European Aviation Safety Agency (EASA) AD 2018-0246, dated November 13, 2018 (“EASA AD 2018-0246”).
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report that due to an issue with the flight warning system (FWS) logic, it is possible that the "AIR Auxiliary Power Unit (APU) BLEED LEAK" electronic centralized aircraft monitoring (ECAM) alert can trigger several times. This AD requires revising the airplane flight manual (AFM) to incorporate procedures related to an APU bleed leak. We are issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2018-0246.
(1) For purposes of determining compliance with the requirements of this AD: Where EASA AD 2018-0246 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2018-0246 does not apply to this AD.
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.
