ATA – Airplane Flight Manual – Abnormal / Normal Procedures Sections –Amendment

Applicability:
Airbus A350-941 and A350-1041 aeroplanes, all manufacturer serial numbers.
Definitions:
For the purpose of this AD, the following definitions apply:
The FOT: Flight Operators Transmission (FOT) 999.0006/20.
The AFM TR: Airbus A350 Airplane Flight Manual (AFM) Temporary Revision (TR) 123 Issue 1.
Reason:Two in-service occurrences were reported involving inadvertent liquid spillage on the ENG STARTpanel or ECAM Control Panel (ECP) on the centre pedestal in the flight deck on A350 aeroplanes. Inboth cases, the aeroplane experienced an un-commanded engine in-flight shut-down (IFSD) of anengine some time after the liquid spillage. Subsequent engine relight attempts were not successful.
In both events, the flight crew performed a diversion and landed the aeroplane safely.

Results of the preliminary technical investigations indicate abnormal operation of the componentsof the ENG START panel or ECP due to liquid spillage in the system.
This condition, if not corrected, could lead to a dual engine IFSD, possibly resulting in a forced
landing with consequent damage to the aeroplane and injury to occupants.
To address these occurrences, Airbus published the AFM TR defining a liquid prohibited zone in thecockpit, and the procedures to be followed in the case of inadvertent liquid spillage on the centre
pedestal. Airbus also published the FOT, reminding operators about the standard practices forhandling liquids in the cockpit to reduce the probability of hazards.
For the reasons described above, this AD requires amendment of the AFM.
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:

EDAirbus AFM TR 123 was published as issue 1, rather than issue 1.1. The issue date on the TR wasamended as well. Consequently, this AD is republished to correct these references.

RAFM Amendment:(1) Before next flight after the effective date of this AD, amend the applicable AFM byincorporating the AFM TR, as defined in this AD, inform all flight crews, and thereafter, operate
the aeroplane accordingly.

PE(2) Amending the applicable AFM of an aeroplane by incorporating an AFM revision, which
includes the same content as the AFM TR, is acceptable to comply with the requirements ofparagraph (1) of this AD for that aeroplane.
