Airbus SAS Airplanes
This AD applies to Airbus SAS airplanes identified in paragraphs (c)(1) through (6) of this AD, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2020-0155, dated July 14, 2020 (“EASA AD 2020-0155”).
(1) Model A320-251N and -271N airplanes.
(2) Model A321-251N, -271N, -272N, -252NX, and -271NX airplanes.
(3) Model A330-243 airplanes.
(4) Model A330-343 airplanes.
(5) Model A330-941 airplanes.
(6) Model A350-941 and -1041 airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-251N and -271N airplanes; Model A321- 251N, -271N, -272N, -252NX, and -271NX airplanes; Model A330-243, -343, and -941 airplanes; and Model A350-941 and -1041 airplanes. This AD was prompted by reports of removable display units (RDUs) found undocked from the hosting display docking stations (DDSs). This AD requires removal of the RDUs or implementation of an operational restriction, and a one-time inspection of the RDU installation onto the DDS and, depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is 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 2020-0155.
(1) Where EASA AD 2020-0155 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0155 does not apply to this AD.
(3) Where the EASA AD specifies “any discrepancies,” those discrepancies include damage or deformity to the DDS tab, a jammed butterfly latch, a RDU that does not engage easily, and a RDU that does not latch.
(4) Where paragraph (3) of the EASA AD specifies a compliance time of “before next flight,” that compliance time does not apply to this AD.
(5) Where AOT A44P001-20-00 and A23L001-20-00, as specified in EASA AD 2020-0155, specify the gap must be equal to or greater than 4.2mm, for this AD, the gap must be greater than 4.0mm.
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.
