1. A method of controlling rotor thrust loading in a turbine engine, the method comprising:
rotating a shaft of the turbine engine to produce a forward thrust;
loading a primary bearing with an axial thrust load from the shaft during the forward thrust;
reducing the forward thrust to less than ten percent forward thrust to produce a thrust crossover;
loading a secondary bearing with the axial thrust load from the shaft during the thrust crossover;
supporting a majority of the axial thrust load with the primary bearing during the forward thrust; and
supporting the majority of the axial thrust load with the secondary bearing during the thrust crossover.
