Pitch-axis actuation and feedback path

During automatic flight, attitude, air-data and guidance inputs are processed by the compatible flight-control computer. The computer sends a drive command to the KS 270C. The servo motor turns through its reduction mechanism and transfers torque through the approved mount or linkage to the elevator control system. Feedback and validity circuits allow the flight-control system to monitor the actuator response and detect abnormal operation.

This closed-loop relationship is important during troubleshooting. A pitch-control fault can originate in the computer, wiring, connectors, clutch, servo motor, feedback circuit, mount, cable tension or airframe linkage. Replacing the servo alone may not correct a problem caused elsewhere in the loop. Maintenance personnel should confirm command input, motor current, rotation, torque, feedback and mechanical freedom using the applicable test procedure.

The physical gear and connector arrangement should be inspected for impact damage, corrosion and unauthorized rework. Any resistance or free play outside the approved limits requires evaluation before installation.

Dimensions, speed and approved mount

Open manufacturer and aviation-parts data give approximate dimensions of 4.605 inches long by 3.925 inches wide by 4.675 inches high. The documented speed for this exact suffix is 2.4 RPM. A published commercial specification lists 28 VDC and 4 amperes and identifies the KM 275 as the associated servo mount in compatible installations. Shipping dimensions or packaged weight should not be confused with the installed servo dimensions and mass.

Other KS 270C suffixes can differ in speed, gearing, wiring, modification level or installation approval. A similar case or the same family name is not sufficient evidence of interchangeability. Selection must use the full 065-00178-2200 Part Number together with the aircraft illustrated parts catalog, autopilot documentation and modification status.

Documented aircraft and autopilot application

Cessna 208 illustrated-parts data identify 065-00178-2200 as a KS 270C pitch servo in King autopilot installations for specific aircraft serial ranges. The same documentation notes later replacement configurations and KFC 225 use in defined ranges. A separate service listing reports removal of an exact-suffix unit from a Cessna 182T. These examples confirm real aircraft use but do not make the servo eligible for every Cessna or every KFC installation.

Before installation, verify aircraft model and serial number, approved autopilot, servo position, mount, connector, modification level and any superseding replacement instruction. Where the aircraft catalog requires a later airframe Part Number or modified servo, that instruction takes priority over a catalog description. Associated computers, sensors and mounts are related equipment, not interchangeable alternatives.

Serviceable supply and ordering information

This 065-00178-2200 KS 270C is offered in Serviceable condition from partner stock with a six-month warranty. The main studio image removes the loose service tag while retaining the exact geometry, output gear, mounting plate, wiring and connectors of the photographed servo. The authentic gallery image preserves the real rear housing and original caution and identification areas for condition review.

For an inquiry, specify Part Number 065-00178-2200, model KS 270C, aircraft model and serial range, autopilot type, pitch-servo position, installed mount, modification requirement, release documents and quantity. Related flight-control units can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Cross-sold servos and computers may operate in the same system but are not represented as direct replacements.
