Models named: A350-941, -1041. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2022-0098, dated June 1, 2022 (EASA AD 2022-0098).

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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 2022-0098.

Unsafe condition

This AD was prompted by an indication that both elevator actuators of the PRIMary flight control computers (PRIMs) were considered faulty due to incorrect instructions with a new PRIM standard and a determination that an updated software standard for the PRIMs must be installed. The FAA is issuing this AD to address the faulty standard, which could lead to loss of control of the elevator surfaces, possibly resulting in loss of control of the airplane.

Affected ADs

This AD replaces AD 2022-11-03, Amendment 39-22053 (87 FR 30402, May 19, 2022) (AD 2022-11-03).
