EASA has issued this Airworthiness Directive concerning the new Airbus A321neo:
Airbus A321-251N, A321-252N, A321-253N, A321-271N, A321-272N, A321-251NX, A321-252NX, A321-253NX, A321-271NX and A321-272NX aeroplanes, all manufacturer serial numbers.
For the purpose of this AD, the following definitions apply:
Affected ELAC: Elevator Aileron Computer (ELAC) unit having Part Number (P/N) 3945129100 with L102 software P/N 3945129114 (data-loadable); or ELAC unit having P/N 3945128220 (non-data-loadable).
The applicable AFM TR: Airbus Aircraft Flight Manual (AFM) Temporary Revision (TR) 766, TR 767, TR 768, TR 769, TR 770, TR 771 issue 2 and TR 772 issue 2, as applicable.
EASA AD No.: 2019-0171
Group 1 aeroplanes are those that have affected ELAC installed.
Group 2 aeroplanes are those that do not have affected ELAC installed.
Analysis of the behavior of the ELAC L102 installed on A321neo revealed that excessive pitch attitude can occur in certain conditions and during specific manoeuvres.
This condition, if not corrected, could result in reduced control of the aeroplane.
To address this potential unsafe condition, Airbus issued the applicable AFM TR to provide operational limitations.
For the reason described above, this AD requires amendment of the respective AFM, with AFM TR, as applicable.
This AD is considered to be an interim action and further AD action may follow.
Required Action(s) and Compliance Time(s):
Required as indicated, unless accomplished previously:
- (1) For Group 1 aeroplanes: Within 30 days after the effective date of this AD, amend the applicable AFM to incorporate the applicable AFM TR, inform the flight crews, and, thereafter, operate the aeroplane accordingly.
- (2) For Group 2 aeroplanes: From the effective date of this AD, before next flight after modification of an aeroplane to install affected ELAC, amend the applicable AFM to incorporate the applicable AFM TR, inform the flight crews, and, thereafter, operate the aeroplane accordingly.
- (3) For Group 1 and Group 2 aeroplanes: Amending the applicable AFM of an aeroplane to incorporate later AFM revisions, which include the same content as the applicable AFM TR, is acceptable to comply with the requirements of paragraph (1) or (2) of this AD, as applicable, for that aeroplane.
