The present disclosure provides methods and systems for assessing a health state of an engine. During a fuel control failure event experienced by the engine, pressure data indicative of a pressure within a fuel combustor of the engine and acceleration data indicative of an acceleration of a shaft of the engine are obtained. The pressure data and acceleration data are compared to a predetermined limit associated with plastic deformation of the shaft of the engine. A maintenance issue for the engine is detected when the pressure data and the acceleration data are beyond the predetermined limit. An alert associated with a negative health state for the engine is issued responsive to detecting the maintenance issue.
