Från incidentrapporten avsnitt 1.1.4:
a. At 0519 hrs during the descent to a cleared level of FL230, ECAM
messages “ENG 1 CTL SYS FAULT” and “ENG 2 STALL” were annunciated
within a short period of time. According to the Commander, a light
“pop” sound was heard and some “ozone” and “burning” smell was
detected shortly before the ECAM message “ENG 2 STALL”
Senare senare:
e. At 0530 hrs, when the aircraft was approximately 45 nm southeast
from VHHH and was about to level off at 8,000 ft AMSL, ECAM message
“ENG 1 STALL” was annunciated.
Så nu är båda motorerna ute, de startade APU: n och lyckades snabbt starta om # 1:
h. The crew moved the thrust levers to check the engine control but
there was no direct response from the engines. The No. 1 engine speed
eventually increased to about 74% N1 with the No. 1 thrust lever in
the CLB (climb) detent position. The No. 2 engine speed remained at
sub-idle about 17% N1, with the No. 2 t hrust lever at the IDLE
position.
Motorn 2 var oförmögen, utan kraft, motorn 1 hade misslyckats, men arbetade tillfälligt även om de inte kunde justera kraften, om de skulle stänga det också för att de skulle ha glidit och troligen skulle ha kraschat med total förlust av liv. De hade inte makt att klättra och hade ett skott vid landning, så de blev jävla att de fick det på landningsbanan, inte en dålig landning med tanke på omständigheterna.
På en humoristisk anteckning, ett annat exempel på pilotunderdrivning:
l. At 0539 hrs, the Commander made another PA advising the passengers
of having “small problem with the engines” with small vibrations and
requesting them to remain seated and follow the directions from the
cabin crew.
