The Overspeed Shutoff Detector (OSSD) features a flanged housing and plunger assembly that activates when the engine initiates an overspeed condition. This condition causes the plunger assembly to contact the frangible link and fracture it. Consequently, the signal controlling the fuel is shut off, shutting down the engine to prevent catastrophic failure. The OSSD device is designed for single use. This design is highly engineered to prevent errant activation.
