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

Applicability*9

This AD applies to Airbus SAS Model A350-1041 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2022-0040, dated March 8, 2022 (EASA AD 2022-0040).

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 2022-0040.

Unsafe condition

This AD was prompted by a report of rejected take-offs after transient engine N1 shaft speed exceedance. The FAA is issuing this AD to address a stuck combined spill valve (CSV) piston of the engine hydro-mechanical units (HMUs), which could significantly reduce engine thrust, and if combined with a loss of the second engine, could possibly result in reduced control of the airplane.

Affected ADs

None.
