Airworthiness Directive · Amendment 39-19711 · Flight controls
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category, except those on which Airbus modifications 113758 and 113759 have been embodied in production.
The FAA is superseding Airworthiness Directive (AD) 2018-22- 13, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2018-22-13 required revising the existing airplane flight manual (AFM) to provide the flightcrew with updated procedures related to inboard aileron fault operations. This AD continues to require that AFM revision, and also requires modification of the electronic centralized aircraft monitoring (ECAM) procedures by installing an Airbus temporary quick change (ATQC) and activating an ECAM temporary change. This AD was prompted by a technical issue detected on the inboard aileron electrohydrostatic actuators that caused potential erroneous monitoring of those actuators. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2018-22-13, with revised compliance language and a corrected TR date. At the applicable time specified in paragraph (g)(1) or (2) of this AD, revise the Abnormal Procedures section of the existing AFM to include the information in Airbus A350 TR 113, Issue 1, dated August 17, 2018, which introduces updated procedures related to inboard aileron fault operations. This may be done by inserting a copy of Airbus A350 TR 113, Issue 1, dated August 17, 2018, into the existing AFM. When Airbus A350 TR 113, Issue 1, dated August 17, 2018, has been included in general revisions of the existing AFM, the general revisions may be inserted into the existing AFM, provided the relevant information in the general revisions is identical to that in Airbus A350 TR 113, Issue 1, dated August 17, 2018, and the TR may be removed. Operate the airplane according to the procedures in Airbus A350 TR 113, Issue 1, dated August 17, 2018. In case any discrepancy is identified between procedures displayed on the electronic centralized aircraft monitoring (ECAM) and procedures stated in the applicable existing AFM, the existing AFM procedures prevail.
(1) For airplanes modified by Airbus modifications 113758 and 113760: Within 30 days after the effective date of this AD.
(2) For airplanes not identified in paragraph (g)(1) of this AD: Within 30 days after November 23, 2018 (the effective date of AD 2018-22-13).
Within 6 months after the effective date of this AD, do the actions specified in paragraphs (h)(1) and (2) of this AD.
(1) Install the Airbus temporary quick change (ATQC) as specified in paragraph (h)(1)(i) or (ii) of this AD, as applicable.
(i) For airplanes with flight warning system (FWS) standard S4/2.0: Install ATQC standard V4 for FWS standard S4/2.0, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-31-P028, dated September 17, 2018.
(ii) For airplanes with FWS standard S5/2.2: Install ATQC standard V4 for FWS standard S5/2.2, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-31-P029, dated September 17, 2018. After installation of ATQC standard V4, ATQC standard V5 for FWS standard S5/2.2 may be installed, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-31-P032, dated February 28, 2019.
(2) Activate ECAM temporary change code No. 27AF, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-31-P030, dated September 17, 2018.
