In the Ondeck Emergency Shutdown Procedure, what is the third action?

• A. ROTOR BRAKE
• B. EFSLs OFF
• C. EMERGENCY ELECTRICAL CUTOFF
• D. EVACUATE

Answer: (A)

In the Ondeck Emergency Shutdown Procedure, actions are performed in a deliberate sequence to quickly secure the helicopter. The rotor brake is the third action because the priority is to first isolate power and prevent fuel flow, reducing fire risk and halting any engine/rotor activity. The typical order is to pull the emergency electrical cutoff, then switch EFSLs off, and only then engage the rotor brake to arrest rotor motion. Evacuation, while important for safety, is not part of the mechanical stop sequence and comes after the rotor is secured or as the situation dictates.
