What should be the first action during an engine fire on takeoff?

In the event of an engine fire during takeoff, the first action should be to shut down the affected engine. This step is critical because maintaining power from a malfunctioning engine poses a significant risk; the fire can escalate, and the remaining engine may also be compromised by the situation. By shutting down the affected engine, you reduce the chances of further damage and allow for a safer approach to controlling the aircraft.

It is also essential to remember that continuing the takeoff or trying to extinguish the fire while the aircraft is in the air can be extremely dangerous. Attempting to extinguish the fire may be futile in the early stages of an engine fire, especially if the aircraft is in a critical phase of flight like takeoff, where immediate control and actions are paramount. Calling for emergency assistance is an important step, but it typically comes after the primary actions of securing the aircraft have been taken.
