Which option completes the LH engine fire sequence after the initial step of moving the thrust lever to IDLE if the LH engine fire light remains on?

• A. LH thrust lever - CUTOFF
• B. LH engine fire button PUSH
• C. Fire bottle - PUSH
• D. All of the above

Answer: (D)

When the LH fire light stays on after you’ve moved the thrust lever to IDLE, you must complete the full fire sequence to both shut off the engine and suppress the fire. First, move the LH thrust lever to CUTOFF to stop fuel flow to the engine. This removes the energy source feeding the fire. Next, push the LH engine fire button to arm the fire suppression system and isolate the engine’s fuel and bleed circuits. Finally, push the Fire bottle switch to discharge the extinguishing agent into the engine area. Taking all three actions ensures the engine is isolated, the extinguishing agent is released, and the fire is controlled.
