BendixKing KS 270A servo 065-0059-23

065-0059-23 is the exact BendixKing Part Number for this KS 270A pitch servo. It is an electromechanical actuator used in compatible automatic flight control systems to apply pitch-axis commands to the aircraft control linkage. The complete -23 suffix identifies this specific configuration and should remain attached to the Part Number in quotations, maintenance records and search data.

The servo is one element of an autopilot installation and cannot control the aircraft independently. A compatible flight-control computer calculates the correction, sends the electrical command and supervises engagement. The KS 270A converts that command into mechanical output. Correct performance also depends on the clutch circuit, power supply, connector wiring, mounting structure and correctly rigged control linkage.

Pitch-command path through the servo

During an engaged pitch mode, aircraft sensors provide information to the autopilot computer. The computer compares the selected condition with the sensed response and commands the pitch servo in the required direction. The KS 270A motor and transmission move the connected cable, chain or linkage so the aircraft pitch control responds. Disconnect logic releases the system according to the approved installation design.

The functional chain can be summarized as aircraft sensors and pilot mode selection → autopilot computer → KS 270A pitch servo → aircraft pitch-control linkage. Some installations also employ a separate electric trim servo to reduce sustained control forces. That trim actuator performs a different function and is not a substitute for this pitch servo even when both units operate within the same autopilot system.

Exact -23 plate information

The original label on the photographed unit identifies model KS 270A Pitch Servo and exact Part Number 065-0059-23. It specifies maximum DC input of 14 V / 5 A or 28 V / 5 A and a weight of 2.6 lb, approximately 1.18 kg. The plate also carries TSO C9c and DO-138 references and identifies Avionics Inc. as the marked manufacturer location for the illustrated unit.

The photographed serial number is 29211. These plate readings are suffix-specific evidence and are not inferred from the -03 product. They still do not replace the approved installation manual for connector pin functions, circuit protection, wire size, output coupling or rigging. Those details must be checked using the revision applicable to the aircraft and 065-0059-23 configuration.

Configuration control and inspection

The main photograph shows the servo housing, mounting plate, output pulley assembly and hardware. The gallery image records the exact -23 label. A KS 270A bearing the -03 suffix may share the model family and some electrical ratings, but it remains a different catalogued configuration. Interchangeability must be supported by BendixKing data and the aircraft approval rather than by appearance or model name alone.

Before installation, inspect mounting points, output components, fasteners, wiring, connector security and signs of abnormal wear. After installation, clutch operation, travel direction, rigging and autopilot response require the prescribed functional test. A pitch-axis complaint can also originate in the computer, sensors, switches, trim system or aircraft linkage, so documented troubleshooting should precede replacement whenever practicable.

Serviceable supply and purchase identification

This 065-0059-23 KS 270A is offered in Serviceable condition from partner stock with a six-month warranty. The offer-list price remains higher than the calculated 1.7 multiplier based on the exact same-condition public comparison, so the confirmed offer value is retained. Release documentation and the serial number assigned to an order are checked before dispatch.

For a quotation, specify Part Number 065-0059-23, model KS 270A, required quantity, aircraft type and paperwork requirement. The autopilot computer, trim servo, mounting bracket, output linkage, connector and wiring are included only when explicitly listed. Related units are available through the Garmin / BendixKing / Honeywell / Collins category. Their presence in the same system does not make them interchangeable replacements.
