Role in the automatic pitch-trim chain

In a typical approved system, a pitch-related command is processed by the autopilot computer. When trim correction is required, the electrical command is routed to the KS 272C. The servo motor and transmission move the connected trim mechanism, while the clutch allows the unit to engage or release in accordance with the installed system logic. Manual electric-trim commands can also use the servo where the aircraft wiring provides this function.

A simplified functional chain is autopilot computer or manual trim switch → aircraft wiring and protection → KS 272C trim servo → trim cable, chain or mechanical linkage → pitch-trim surface or mechanism. The exact arrangement differs among aircraft installations. It must be checked against the aircraft maintenance manual and BendixKing installation data before replacing, rigging or functionally testing the unit.

Electrical and performance references

The exact identification plate on the photographed 065-00180-2700 unit specifies 28 V DC input and a 4 A rating. Reviewed KS 272C maintenance information lists a manual-trim operating-voltage range of 18.5 to 25.5 V and identifies clutch control at connector pin F for the applicable test procedure. These figures describe controlled shop or system checks and do not replace aircraft-specific circuit limits.

The same maintenance data gives an output speed of one revolution in 17 to 20.5 seconds and a load reference of 80 lb, equivalent to 71 in-lb for the documented test. These values are useful for identifying correct servo response during approved bench testing. They should not be converted into installation limits without considering the specified fixture, supply voltage, clutch state and applicable revision of the maintenance manual.

Identification, installation and inspection

The photographed plate reads KS 272C Trim Servo, Part Number 065-00180-2700 and serial number 3309. It also carries TSO C9c and DO-160C references and identifies Honeywell International. The gallery image preserves the actual plate rather than replacing it with a label from another KS 272C suffix. This is important because suffix-level configuration cannot be established from the housing alone.

Installation inspection should include the mounting points, output coupling, wiring condition, connector security, clutch operation, travel limits and trim-system rigging. Uncommanded movement, abnormal running time or clutch slip can originate outside the servo as well as inside it. Exact dimensions, connector pin functions and rigging values are therefore left to the approved KS 272C and aircraft documentation where the reviewed open sources did not provide dependable suffix-specific figures.

Serviceable unit and quotation requirements

This 065-00180-2700 KS 272C is offered in Serviceable condition from partner stock with a six-month warranty. The price follows the agreed rule and uses the higher value between the offer list and 1.7 times the exact same-condition public comparison. Photographs show the authentic unit and exact plate; allocated serial number and release documents are reconfirmed before shipment.

For a quotation, specify Part Number 065-00180-2700, model KS 272C, quantity, aircraft application and paperwork requirement. Mounting brackets, cable or chain hardware, mating connector, controller and other autopilot units are supplied only when explicitly stated.
