Fire extinguishing capability is not provided for which component?

• A. APU Bay
• B. MGB Compartment
• C. Cockpit
• D. Cargo Compartment

Answer: (B)

Fire protection in the MH-65E is arranged so that extinguishing capability is provided where practical for critical areas, while some spaces rely on detection and isolation rather than discharge of agent. The main gear box compartment is not equipped with a fire extinguishing system. Introducing an extinguishing agent into an oil-filled gearbox could contaminate lubrication, damage bearings, and be difficult to purge during flight, so protection relies on early fire detection and the ability to shut down the powerplant to stop fuel and heat, containing the fire and allowing a safe completion of flight or landing. In the other spaces—APU bay, cockpit, and cargo compartment—fire suppression is provided to protect crew, powerplant, and cargo, making the gearbox area uniquely without extinguishing capability.
