Unsafe Condition
A broken aileron servo actuator centering spring rod was discovered on a model G100 aircraft. This latent failure, if not detected and corrected, in conjunction with the disconnection of the normal mechanical control system of the same servo actuator, would lead to loss of control of the flight control surface (aileron or elevator).
