A tailpipe fire ensued when motoring caused the left engine’s propeller to rotate. Without radio communication or headsets available for verbal exchange between marshaller and crew, non-standard hand signals were used unsuccessfully to communicate during this critical phase.
"As the marshaller and flight crew were not able to communicate verbally (there was no radio and no communications headset for the Saab 340), the marshaller reported they tried to signal to the captain to shut the engine down using a ‘cut-throat’ hand signal."
Despite rising interstage turbine temperature (ITT), which prompted further motoring attempts by the captain, flames were neither visible from inside nor indicated by cockpit instruments. Ultimately, an emergency checklist procedure was initiated after confirming an engine fire at 14:46 local time.
"All right, mate, fire," remarked one pilot during these procedures. Following this acknowledgment of fire risk within seconds both primary and secondary extinguishing measures were activated; however initial items on corresponding checklists had been omitted under stress conditions prevailing then: "The captain later recalled that they omitted two engine fire checklist items relating to power and condition levers […] due to stress at time."
