"textContent": "An accessory gearbox detachment system includes a vibration sensor, a shape memory alloy (SMA) actuator, and a processing system. The vibration sensor is mounted on an accessory gearbox and senses vibration levels of the accessory gearbox and supplies sensor signals indicative thereof. The SMA actuator is mounted within the accessory gear box and is configured, upon receipt of an activation signal, to move from an engage position to a disengage position. The processing system is in operable communication with the at least one SMA actuator and the vibration sensor. The processing system is configured to receive and process the sensor signals to determine a vibration level of the accessory gearbox, compare the vibration level to one or more predetermined threshold values, and supply the activation signal to the at least one SMA actuator when the determined vibration level exceeds the one or more predetermined threshold values.",
