With both engines inoperative, and using its remaining speed, the aircraft left Runway 07 entering taxiway B, where it came to a stop. The cockpit crew of AWAIR flight QZ730 reported executing the engine shutdown and fire-extinguishing procedures, meanwhile monitoring the engine gas temperature (EGT).
At about the same time Air Traffic Control informed the flight crew that engine #1 was on fire. The AWAIR flight QZ730 crew reported there was no fire warning, and that the Engine Gas Temperature, EGT, was increasing even after the fuel was cut-off. The cockpit crew concluded that apparently a tail pipe fire on both engines had occurred. The cockpit crew requested the assistance of a towing car to tow the aircraft to the parking place. Meanwhile the fire fighting was converging to the aircraft and starting to spray extinguishing foam into both the engine tail pipe nozzles.
