Question 225Motor Plants - 1st Asst/Chief

The correct answer is C) Failure to reset the overspeed trip. The overspeeding and failure to restart are indicative of an overspeed trip that has been activated on the engine. The overspeed trip is a safety mechanism designed to shut down the engine if it exceeds a maximum preset speed to prevent damage. If the overspeed trip is not properly reset after an overspeed event, the engine will be unable to restart until the trip is reset. This is the most likely cause of the engine failing to restart in this scenario. The other options are incorrect because they do not directly address the issue of the overspeed trip being activated. Failure to reposition the fuel rack, improper governor operation, or damage to the governor would not necessarily prevent the engine from restarting if the overspeed trip had been reset properly.
