An Airbus A350-900 operated by Delta Air Lines, was conducting flight DL159 from Detroit (KDTW) MI, USA to Seoul (RKSI), Korea. En route, about 735 nautical miles north of Yellowknife (CYZF), NT, the aircraft experienced surging in the no.2 engine (Rolls Royce Trent XWB-84, S/N 21390) which led to a roll back and subsequent shutdown. The flight crew, in consultation with dispatch, elected to divert to Fairbanks (PAFA), Alaska. The aircraft landed without further incident.
The aircraft was ferried to Minneapolis and resumed service on January 23.
On February 7, 2020, an emergency AD was issued by EASA, reporting:
"Two in-service occurrences were reported involving inadvertent liquid spillage on the ENG START panel or ECAM Control Panel (ECP) on the centre pedestal in the flight deck on A350 aeroplanes. In both cases, the aeroplane experienced an un-commanded engine in-flight shut-down (IFSD) of an engine 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."
To address these occurrences, Airbus published the applicable AFM TR defining a liquid prohibited zone in the cockpit, 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 for handling liquids in the cockpit to reduce the probability of hazards. The EAD requires amendment of the AFM.
