Collins Aerospace SVO-3000 Primary Servo & Mount

This listing is for a complete, matched primary autopilot actuator assembly combining the Collins Aerospace SVO-3000 Primary Servo (P/N: 822-1168-002) and its corresponding Collins SMT-65 Servo Mount (P/N: 622-5735-021). Integrated into the Pro Line 21 automatic flight control architecture, this combined system receives electronic stabilization signals from the autopilot computer and converts them into physical, automated displacement of the aircraft's primary control lines—most frequently utilized on the aileron flight tracking axis.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 7/21/2026.

Key Technical Capabilities
  • High-Torque Friction Parameters: The 622-5735-021 mounting assembly features an internal, adjustable override clutch rated for a high-torque mechanical profile (ranging up to 177 lb-in). This configuration provides firm authority over primary aerodynamic control lines subjected to heavy structural wind loads.
  • Aileron/Roll Axis Optimization: The electronic and mechanical gear reductions inside the 822-1168-002 drive assembly are specifically calibrated to deliver steady, high-precision micro-adjustments along the aircraft’s lateral roll profile.
  • Structural Maintenance Splitting: The architectural interface of the SMT-65 mount allows maintenance personnel to unbolt and replace the electrical SVO-3000 drive motor for service without detaching the capstan assembly or altering the baseline cable rigging tension of the aircraft’s physical flight systems. 
  • Manual Overpower Protection: Built with safety redundancies, the mechanical override clutch permits smooth slip operation if a motor jam or electronic runaway occurs. This layout ensures the flight crew can safely overpower the assembly by applying manual force to the control yoke.
  • Environmental and RFI Shielding: Operating within a standard 28 VDC nominal avionics architecture, the internal permanent-magnet motor is dynamically isolated to suppress electromagnetic noise, preventing interference with neighboring digital flight deck electronics.
