Lessons Learned
The auto-throttle was disengaged in order for the first officer to manually reduce thrust on the right engine. Within two seconds of the thrust reduction on the right engine, the left engine fan speed stabilized at a level 3% below its previous stable value, and the EGT stabilized at about 50ºC above the previous stable value. However, the left engine fuel flow was still behaving erratically and continued to drop. The AVM continued to show a vibration value of five units. It was noted in the accident report that "the captain later stated that the action of closing the right engine throttle reduced the smell and the visual signs of smoke and that he remembered no continuation of the vibration after the right throttle was closed.
