Narrative:

Started the descent to cross the waypoint slightly behind schedule with deployed speed brakes and dialed in 3;000 FPM descent. At this time we had a main pitch trim failure and continued with the memory items for the pitch trim runaway. We followed the QRH to trouble shoot the problem. We followed the procedures and landed safely. Complacency; distraction and too much confidence in the FMS in regards to descent planning. Never be too complacent with the FMS and always be concentrated on flying the airplane and keeping the communication open between pilot flying and pilot not flying.
