BendixKing KS 271C roll servo 065-00179-0100

065-00179-0100 is the exact Part Number for this BendixKing KS 271C primary roll servo. The electrically driven actuator forms part of compatible automatic flight-control installations and converts commands from the flight-control computer into controlled mechanical motion. In a roll-axis application, that motion is transferred through the approved servo mount, capstan or linkage to the aircraft control system.

The KS 271C is not an independent autopilot and does not calculate roll commands on its own. It receives electrical drive commands from compatible equipment and returns velocity or validity information used by the control system. A typical chain is aircraft attitude and guidance inputs to the flight-control computer, electrical command to the KS 271C, mechanical output through the approved mount, and resulting movement in the aircraft control linkage.

Servo drive, feedback and torque function

Published service data describe the KS 271C as a 28-volt DC motor-driven servo with velocity feedback and a validity signal to the flight-control computer. The exact 065-00179-0100 configuration is identified as a 3.6 RPM primary or roll servo. Maximum torque is reported as 100 inch-pounds, with maximum current of approximately 4 amperes under the documented test conditions.

Feedback is essential because the computer must monitor servo response rather than simply apply uncontrolled motor power. A fault can therefore originate in the servo motor, feedback circuits, clutch or linkage, flight-control computer, wiring or mechanical installation. Troubleshooting should confirm freedom of movement, command and feedback signals, torque behavior and mount condition using the approved maintenance procedure.

Dimensions, mounting and exact configuration

Published physical data give approximate dimensions of 3.925 inches by 4.675 inches by 4.605 inches and a weight of about 2.2 pounds. The KS 271C is used with an approved servo mount; published references associate it with the KM 276 mount in compatible installations. The mount, capstan, cable or linkage hardware is separate equipment unless expressly included in the commercial quotation.

Other KS 271 or KS 272 family units can have different speed, torque, axis assignment, mount, connector or approval. They must not be described as interchangeable solely because the housings appear similar. The complete 065-00179-0100 Part Number, system drawing, aircraft application and modification status must agree before replacement. The precise cable geometry and clutch adjustment remain aircraft-specific.

Flight-control integration and maintenance checks

Open service references place KS 271C servos in compatible BendixKing KFC flight-control systems, including KFC 140 and KFC 225 family installations as configured. Aircraft examples appear in approved parts and maintenance data, but applicability varies by model, serial range and modification. A Cessna 208 reference is not universal permission to install the servo in every Cessna or every KFC-equipped aircraft.

Receiving inspection should verify Part Number 065-00179-0100, model KS 271C, connector leads, output shaft, mounting holes, enclosure, evidence of corrosion and release documents. Bench testing should confirm winding condition, current, rotation speed, torque, clutch action, velocity feedback and validity output. Installed testing must also verify linkage travel, cable tension where applicable and correct roll-axis response without binding.
