Methods for detecting events, e.g., failures, in actuating systems for turbine engines are provided. In one exemplary aspect, a first slope and a second slope are determined. The first slope is determined by calculating the slope of an engine operating characteristic as a function of time prior to an actuation command. The second slope is determined by calculating the slope of the engine operating characteristic as a function of time after the actuation command. Thereafter, a delta slope is generated based at least in part on the difference between the first slope and the second slope. The delta slope is then compared to a predetermined threshold to determine whether a failure in the actuating system has occurred. Turbine engines configured to detect such events are also provided.
