CRJ200 flight crew discovers that the right engine is unresponsive to thrust lever movement when attempting to retard thrust for descent. An emergency is declared; the engine is shut down; and a single engine landing ensues.

Narrative:

First officer was flying and was issued a crossing restriction. Immediately after pulling the thrust levers back to initiate the descent the first officer saw that the right engine was unresponsive to thrust lever inputs. First officer called for the QRH and the captain ran the jammed thrust lever QRH procedure. The captain and the first officer agreed to keep the engine running until 10;000 feet and closer to ZZZ. The first officer deployed flight spoilers to continue the descent because the right engine N1 was at 98 percent. The captain kept the passengers and flight attendant informed of everything. Once level at 12;000 feet and complying with the crossing restriction the captain completed the thrust reverser jammed QRH procedure and used the fire push switch to shut down the right engine. An emergency was declared and the ILS was requested to maximize the runway length. First officer kept the PF role and landed the airplane safely. The captain took controls and taxied to the gate. Passengers were deplaned without compromising safety. The flight crew attempted to swap the bleeds to the APU above 15;000 feet but the other crew member quickly noticed and prevented it. The flight crew with no guidance from the checklist attempted to 'test' the thrust lever by moving it forward increasing the N1 to 98 percent where it stayed.

Title: CRJ200 flight crew discovers that the right engine is unresponsive to thrust lever movement when attempting to retard thrust for descent. An emergency is declared; the engine is shut down; and a single engine landing ensues.

Narrative: First Officer was flying and was issued a crossing restriction. Immediately after pulling the thrust levers back to initiate the descent the First Officer saw that the Right Engine was unresponsive to thrust lever inputs. First Officer called for the QRH and the Captain ran the Jammed Thrust Lever QRH procedure. The Captain and the First Officer agreed to keep the Engine running until 10;000 feet and closer to ZZZ. The First Officer deployed Flight Spoilers to continue the descent because the Right Engine N1 was at 98 percent. The Captain kept the passengers and Flight Attendant informed of everything. Once level at 12;000 feet and complying with the crossing restriction the Captain completed the thrust reverser jammed QRH procedure and used the fire push switch to shut down the Right Engine. An emergency was declared and the ILS was requested to maximize the runway length. First Officer kept the PF role and landed the airplane safely. The Captain took controls and taxied to the gate. Passengers were deplaned without compromising safety. The flight crew attempted to swap the bleeds to the APU above 15;000 feet but the other crew member quickly noticed and prevented it. The flight crew with no guidance from the checklist attempted to 'test' the Thrust Lever by moving it forward increasing the N1 to 98 percent where it stayed.
