Pitch-axis function in an autopilot system

When the autopilot requests an elevator correction, the flight-control computer sends an electrical command to the pitch servo. The KS 270A motor and transmission then move the connected linkage in the required direction. Feedback and clutch arrangements within the approved system allow the computer to control the response and permit disengagement according to the aircraft installation design.

A simplified chain is aircraft sensors and pilot-selected mode → compatible autopilot computer → KS 270A pitch servo → aircraft pitch-control linkage. A separate trim servo may relieve sustained pitch forces in installations that provide automatic electric trim. The KS 270A pitch servo and a trim servo perform different jobs and should not be presented as substitutes for one another.

Exact -03 electrical ratings

The original identification plate on the photographed unit gives Part Number 065-0059-03 and identifies the equipment as a KS 270A Pitch Servo. It specifies maximum DC input of 14 V / 5 A or 28 V / 5 A. The plate also lists a weight of 2.6 lb, approximately 1.18 kg, and carries TSO C9c and DO-138 references.

These values belong to the exact -03 unit shown in the gallery and are preferable to generic family data. They do not establish aircraft circuit-breaker size, wire gauge, connector pinout or permissible duty cycle. Those installation values must be taken from the current BendixKing manual and aircraft-specific approval. Applying family figures without suffix confirmation can lead to incorrect replacement selection.

Identification and installation inspection

The photographed serial number is 29150. The main image shows the housing, mounting flange, output side, wiring lead and connector, while the gallery image records the original label. The images preserve the authentic configuration and do not substitute a -23 servo. This distinction matters because the -03 and -23 variants are separate catalogued Part Numbers even when the basic model name is the same.

Before installation, maintenance personnel should verify the mounting arrangement, output coupling, cable or chain condition, connector security, clutch function, mechanical travel and autopilot rigging. A system fault can originate in external wiring, control linkage, trim equipment, sensors or the computer, so servo replacement should follow documented troubleshooting. Exact dimensions and connector details are intentionally referred to approved data where dependable -03 figures were not available in the reviewed public material.

Serviceable condition and controlled ordering

This 065-0059-03 KS 270A is offered in Serviceable condition from partner stock with a six-month warranty. The commercial value follows the confirmed offer list; no higher exact same-condition public comparison was available for this suffix. Release paperwork, test status and the serial number allocated to an order are confirmed in the quotation and shipping documents.

For a quotation, specify Part Number 065-0059-03, model KS 270A, required quantity, aircraft application and document requirement. Autopilot computer, trim servo, mounting hardware, linkage parts and mating connector are included only if expressly listed. Related system units can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Related equipment may share an aircraft system but does not constitute an approved interchangeable replacement.
