Part 4/9:
Barely 25 seconds post-takeoff, both engines began surging—a result of compressor stalls prompted by the ice collision. While pilots are trained for various emergencies, they had not received specific training on handling engine surges, leading to a critical knowledge gap. Instead of instinctively implementing necessary procedures to mitigate the surge, the crew frantically searched for answers among cockpit checklists, which would prove to be too little, too late.
As panic set in, the first officer realized the engine was surging and attempted to reduce power, but the aircraft was equipped with an Automatic Thrust Restoration (ATR) system that counteracted their attempts to manage the engines manually.
