            Background:  The pitch servo actuator of model AK523 Edo-Aire Mitchell Century III autopilot can, under specific conditions, force the servo capstan arm over centre. This condition restricts the limits of travel of the elevator control system. Incorporation of the SB will prevent such a condition.
