NTSB Narrative Summary Released at Completion of Accident
THE AIRCREWS OF A UNITED DC-10 (FLT 99 HEAVY) AND TWO U.S. AIR DC-9'S (FLT 25 AND FLT 199) TAXIED FOR TAKEOFF AT ABOUT THE SAME TIME. DUE TO DELAYS, THE NO. 2 ENGINE OF FLT 199 WAS SHUT DOWN IN ACCORDANCE WITH APPLICABLE FUEL CONSERVATION PROCEDURES. AFTER FLT 99 WAS CLEARED FOR TAKEOFF, THE AIRCREW OF FLT 199 STARTED THEIR ENGINE, BUT IT TORCHED AND EMITTED FLAMES FROM THE TAIL CONE. THE CAPTAIN OF FLT 25 SAW THE FLAMES AND TRANSMITTED ON TOWER FREQUENCY, "99, YOU'RE RIGHT ENGINE'S ON FIRE." AT ABOUT THAT TIME, UNITED FLT 99 HEAVY WAS LIFTING OFF. THINKING HE HAD AN ENGINE FIRE, THE CAPTAIN OF UNITED FLT 99 HEAVY ABORTED ABOVE V1/VR RATHER THAN CONTINUING INTO A LOW CEILING WITH FOG AND RAIN. THE CAPTAIN THOUGHT HE COULD STOP ON THE HARD SURFACE, BUT WAS UNABLE. THE PLANE CAME TO REST ON MUDDY TERRAIN. ONE PASSENGER WAS INJURED DURING EVACUATION. DURING THIS SEQUENCE, THE TOWER CONTROLLER WAS UNABLE TO SEE THE RUNWAY DUETO THE LOW VISIBILITY (3/8 MI).
