Aircraft
Pitch trim failed during final approach approximately 1;000 FT-1;500 FT AGL. Autopilot was not engaged at the time. The Captain pushed and held the 'trim in/autopilot disengage' switch to prevent the trim from moving and instructed me to switch the pitch from 'NORM' to 'EMER.' The emergency trim worked sufficiently to control the airplane and we continued and landed. Upon landing and clearing the runway we ran the Emergency Checklist for 'Pitch Trim Runaway or Failure' and promptly notified Maintenance. The trim worked fine during the flight until the time of failure.
