Airbus SAS Airplanes
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”).
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-214, A320-232, A320-233, A321-211 and A321-231 airplanes. 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. This AD requires a replacement of affected RAT actuators. 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 2018-0256.
(1) For purposes of determining compliance with the requirements of this AD: Where EASA AD 2018-0256 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2018-0256 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.
