Collins Aerospace SVO-3000 Primary Servo
This listing is for a matched autopilot flight control assembly combining the Collins Aerospace SVO-3000 Primary Autopilot Servo (P/N: 822-1168-001) together with the matching Collins SMT-65 Servo Mount (P/N: 622-5735-022). Functioning as a critical node in the Pro Line 21 flight guidance architecture, this integrated package converts electronic stabilization commands from the autopilot computer into physical, automated displacement of the aircraft’s primary control surfaces (typically configured for elevator, aileron, or rudder axis tracking).
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
- System Component Integration: The SVO-3000 servo motor bolts directly onto the SMT-65 mounting frame. This design allows the electronics and internal drive motor to lock seamlessly with the mechanical capstan gear that drives the main aircraft control cables.
- Low-Torque Precision Output: The 822-1168-001 servo is rated for a continuous-duty 60 lb-in torque profile. This parameter delivers smooth micro-corrections required for high-altitude cruise stabilization without over-stressing lighter primary flight control lines.
- Independent Maintenance Decoupling: The architecture of the SMT-65 mount allows maintenance technicians to detach and replace the electrical SVO-3000 servo unit for servicing or test bench calibration without having to de-rig or release cable tension from the aircraft’s underlying mechanical flight control lines.
- Mechanical Overpower Safety Clutch: The servo mount incorporates an internal, adjustable friction slip clutch mechanism. If the electric servo motor experiences a terminal jam or an electronic runaway condition, the clutch slips under manual pilot pressure, allowing the flight crew to physically override the autopilot and retain manual command of the flight path.
- Pro Line 21 Architecture Support: Engineered for multi-engine piston, turboprop, and light jet applications utilizing Collins Pro Line 21 avionics suites. The assembly is optimized for low electrical noise generation and minimal power distribution footprints on standard 28 VDC nominal avionics buses.
