Analysis

During descent the B727 crew noted the fire warning light illuminate on the #1 engine. They discharged 2 fire bottles into the engine but the warning light remained illuminated. They declared an emergency and landed at their destination. An emergency evacuation was conducted, and 4 passengers received minor injuries. Examination revealed that the 13th stage bleed air duct line to the fuel heater was leaking at the input side and was impinging on a fire detection loop about 2 inches from the leak.
