Engine Fire Warning and Starter Turbine Failure During Takeoff (N189FE)

Incident Overview and Crew Response During takeoff, the aircraft reached 100 feet above ground level (AGL) using standard power when the #3 engine fire warning light illuminated, despite normal engine indications. While the captain and second officer performed the engine fire/severe damage checklist, the #3 oil low pressure light came on and the #3 generator tripped off. The fire warning light remained illuminated until the second fire bottle was discharged. The crew declared an emergency to the tower, made a normal landing, and taxied clear of the runway. Emergency crews inspected the aircraft and found no indication of fire. The aircraft subsequently taxied back to the gate and completed a normal shutdown.
