Killaroo,
The earlier publication “Accident Bulletin 1/2011 (An update Bulletin to Accident Bulletins 1/2010 and 3/2010)”
includes a paragraph 5, copied below (my bold):
“5. At 0530 hr, the ECAM caution message “ENG 1 STALL” was annunciated. The commander moved the No. 1 thrust lever to idle position. He then tested the engines by gently advancing and retarding the thrust levers. However, only No. 1 engine responded with stepped increase in N1 and did not reduce when the thrust lever was retarded. No. 2 engine remained at idle during the test.
In an attempt to recover No. 2 engine control, the crew carried out a shutdown and restart on No. 2 engine in accordance with the Flight Crew Operating Manual (FCOM) procedures. However, the engine could only operate at sub-idle condition for the remainder of the flight. The No. 1 engine was stuck at approximately 74% N1 during the approach and reduced to about 70% N1 at touchdown. The No. 2 engine remained stuck at about 17% N1 throughout the approach and landing.”
One can only speculate as to the engine delivered and aircraft required thrust behaviour and consequences that would occur if Engine 1 had also been shutdown.
J.O. said it rather well
Those boys did a whale of a job in a situation none of us has ever even contemplated, never mind being trained for it.
