A method for monitoring service load on airborne vehicle components is provided. The method includes: extracting, from an airborne vehicle after completing a mission, the start and end time of each of a plurality of flight regimes and flight parameters of interest for each of the plurality of flight regimes; generating, for each regime, a time domain spectrum of the stress spectrum for each regime/events/maneuvers actually encountered in the mission from the extracted flight parameters; determining flight conditions experienced during the planned mission; determining a stress per G spectrum corresponding to the experienced flight conditions, wherein the stress per G spectrum identifies an amount of stress experienced by the airborne vehicle at fatigue critical locations per G of air load experienced at the fatigue critical locations; and determining an air load stress spectrum for the airborne vehicle by multiplying the time domain spectrum data with corresponding stress per G spectrum data.
