What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)While holding and waiting for take-off clearance at the 27L run up pad, a fire warning (later confirmed false) was indicated in the #2 engine. The warning bell, engine fire warning annunciator light and fire button ("handle") initially activated intermittently and was erratic and then resumed. The flight crew advised ATCT of an engine fire and initiated a shutdown of the #2 engine. The #2 squib was then fired, the warnings ceased momentarily and then continued. With both engines shut down, ATCT was notified and a precautionary evacuation was intitiated. The first officer exited the aircraft to marshal the passengers deplanned via the main cabin door. The #1 squib was fired after the warnings resumed continuously and within ten seconds after the first (#2) squib was fired. The warnings then stopped. The deplanning was orderly and without injury. The passengers were buses to the terminal. The ord fire dept responded and escorted the aircraft as it was towed to the company's gate. A preliminary investigation by the company's maintenance department, witnesses by FAA ord FSDO personnel, revealed no evidence of fire. A log entry prior to the subject flight, entered th y before, indicated a fault with the fire warning system of the #2 engie had been cleared. Maintenance subsequently confirmed and repalced a faulty #2 engine fire detection control unit, p/n 51653, s/n 2060. See crew reports in attached fax, dated 9/12/00. Incident closed. Dpa NTSB (e.m) and aeg (j.g) notified.
