Primary-servo role in the control chain

A typical control path is aircraft sensors and pilot-selected mode → flight-control computer → KS 271A primary servo → approved capstan or mount → aircraft control cable or linkage. The servo motor produces the requested movement while the system clutch and disconnect circuits allow engagement and release in accordance with the approved design. Exact mechanical direction and travel depend on installation rigging.

Official KAP/KFC 200 documentation identifies a KS 271/A with a KM 275 mount as the roll servo. The same system family can use a KS 271/A in the optional yaw channel with its approved mounting arrangement. This confirms the functional family but does not prove that every KS 271A suffix is interchangeable. The aircraft drawing, mount number, capstan, wiring and complete Part Number remain decisive.

Exact electrical and weight data

The original plate on the photographed unit identifies it as a KS 271A Primary Servo with Part Number 065-0060-01. It specifies maximum DC input of 14 V / 5 A or 28 V / 5 A. The plate gives a weight of 2.4 lb, approximately 1.09 kg, and carries TSO C9c and DO-138 references. These values are taken from the exact unit rather than from another KS 271A suffix.

The photographed serial number is 44096. The label also shows modification status markings, which must be evaluated together with the release documentation for the unit allocated to an order. Plate values do not replace aircraft circuit-breaker, wire-gauge or connector-pin requirements. Those limits are installation-specific and must be taken from the current BendixKing and aircraft technical data.

Mounting, rigging and configuration checks

The main image shows the original housing, mounting plate, output pulley, lead, connector and fasteners. The reseller label has been removed without changing the servo geometry or the genuine ROLL label visible on the illustrated unit. The gallery view preserves the exact identification plate and serial reference. No visually similar KS 270A or KS 272A image has been substituted.

Before installation, technicians should confirm the servo position, mount and capstan, connector keying, wiring, clutch operation, control travel and cable tension. After installation, direction, engagement, disconnect and system response require the approved functional test. A roll or yaw complaint may originate in sensors, the flight computer, wiring, linkage or mount, so replacement should follow documented troubleshooting.

Serviceable supply and ordering information

This 065-0060-01 KS 271A is offered in Serviceable condition from partner stock with a six-month warranty. The price is the higher value required by the agreed rule after comparison with the exact same-condition public position. Serial number, release paperwork and test status for the supplied unit are confirmed in the quotation and dispatch documents.

For an inquiry, specify Part Number 065-0060-01, model KS 271A, intended aircraft, control axis, quantity and required documentation. The flight computer, mount, capstan, connector, linkage and wiring are included only when expressly stated.
