Models named: A320-214, A320-232, A320-233, A321-211, A321-231. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus SAS Model A320-214, A320-232, A320-233, A321-211, and A321-231 airplanes; certificated in any category; as identified in the European Aviation Safety Agency (EASA) AD 2018-0256, dated November 28, 2018 (“EASA AD 2018-0256”).
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 2018-0256.
Unsafe condition
This AD was prompted by an investigation that revealed that the outer cylinder of a certain ram air turbine (RAT) actuator was not properly deburred in accordance with manufacturing specifications. We are issuing this AD to address the improperly deburred outer cylinder of the RAT actuator, which could block the hydraulic circuit with metallic parts and result in failure of the RAT actuator to extend during certain emergency conditions for generation of hydraulic or electrical power, which may lead to reduced control of the airplane.
Affected ADs
None.
