Narrative:

During the initial descent; the #2 was non-responsive. The engine continued to operate at cruise power despite numerous attempts to adjust it both with and without autothrottles. It was difficult to plan and meet altitude restrictions in the descent despite using full boards. Because there appeared to be no imminent danger of exceeding any engine tolerances; the engine was kept running and all maneuvering was done with the #1 throttle at idle and controlling the speed with drag devices. We got vectors for a 20-mile final and determined that it was not possible to control the speed on the approach with the engine stuck at cruise power. We declared an emergency; shut down the #2 engine and landed uneventfully. I cleared the runway and had fire/rescue inspect the engine. No apparent damage was found. We were then towed to the gate.

Original NASA ASRS Text

Title: An A300 number two engine thrust was not adjustable and maintained cruise power with autothrottles ON or OFF. Because speed control became difficult during the approach; the engine was shutdown; an emergency declared and a normal landing followed.
