The aircraft was descending from FL410 with the throttles at idle. As power was added at FL295 the left engine surged and exceeded maximum EGT. Eighteen seconds later the right engine surged and exceeded its maximum EGT. The left and right engines were shut down at FL200 and FL177 respectively. The engines were successfully restarted about FL150. The inability of the engines to accelerate after the manually induced surge was due to contaminated fuel nozzles which significantly reduced combustion chamber efficiencies & which resulted in a subidle stall. On March 31, 1986 this same aircraft (N609UA) again suffered a double engine flameout.
