Overview
A flight experienced a false fire warning during its descent at night, leading to an emergency evacuation on the runway after landing. The incident resulted in serious injuries to two passengers.
Incident Details
While passing through 10,000 feet MSL on the descent for a night landing, the number two engine fire warning light and bell activated. The flight crew completed all applicable checklist procedures, but the fire warning indications remained on. The captain decided to conduct an emergency evacuation on the runway after the airplane landed.
Evacuation and Injuries
During the evacuation, one passenger was knocked off the wing by another passenger who was overzealous and suffered serious injuries. In a separate incident, a passenger with two small children requested assistance from a flight attendant. While the flight attendant was seeking help, the passenger placed one child onto the evacuation slide without waiting for assistance. The child resisted and fell from the slide, also sustaining serious injuries.
Post-Flight Examination
A post-flight examination of the airplane revealed a faulty fire detection element on the number two engine. No evidence of an in-flight fire was observed.
