During NP overspeed, fuel shutoff occurs at which component?

Explanation:
During NP overspeed, the automatic safety shutoff is handled by the Overspeed Disconnect Valve. This valve sits in the engine’s fuel-control path and closes to cut fuel flow when rotor speed exceeds the safe limit, protecting the engine and rotor from damage. The pilot’s Power Control Lever controls normal fuel flow during regular operation, but it does not automatically shut fuel off in an overspeed event. The other components mentioned are not involved in delivering an automatic fuel shutoff during an overspeed, so they don’t serve this protective role.
