S-TEC Autopilot Pitch Trim Servo

This part number designates a panel-or-airframe mounted, high-torque electric autopilot trim servo assembly manufactured by S-TEC Corporation. It serves as a baseline flight control subsystem designed to provide automated pitch trim adjustments. It interfaces directly with higher-tier S-TEC automated flight control systems, including the S-TEC System 55, 55X, and 60 series configurations.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 06/03/2026.

This specific -T2 variant is built for a 28 VDC nominal power environment and is commonly factory-configured or STC-installed on high-performance general aviation platforms, specifically the Beechcraft Baron series (such as the 95-B55 or 58).

Key Technical Capabilities
  • Automatic Trim Coordination: Continuously communicates with the primary autopilot pitch computer to execute automated aerodynamic trim updates. This relieves sustained control-wheel pressure on the pitch servo during steady state climbs, descents, and atmospheric variations. 
  • Precision Electromechanical Drive: Utilizes an internal, high-efficiency electric motor and internal gear reduction profile to drive an external flight control cable pulley, delivering minute adjustments to the aircraft’s pitch trim tab system. 
  • Integrated Bridle Cable Interface: Designed to secure seamlessly into the airframe’s trim control system using dedicated mounting brackets and specialized cable guards to prevent primary aircraft cable fouling or slippage during high-G or high-workload maneuvers. 
  • Rigid Metal Housing Profile: Housed in a heavy-duty, corrosion-resistant metallic casing built to isolate the internal electrical winding circuits and sensors from severe engine vibration profiles and thermal shifts inside unpressurized tailcones or under-floor spaces.
