BendixKing KC 140 computer 065-00176-7703

065-00176-7703 is the exact BendixKing Part Number for this KC 140 flight control computer. The unit is a central cockpit component of a compatible KAP 140 automatic flight control installation. It combines the pilot control interface, mode annunciation and flight-control computing functions in a single panel-mounted assembly. The complete Part Number, including the -7703 suffix, should be matched to the aircraft equipment list and approved installation data before ordering.

The KC 140 is not a complete autopilot by itself. It receives pilot selections and system inputs, processes the applicable control logic and sends commands to compatible servos installed in the aircraft control system. Availability of individual modes depends on the aircraft configuration, installed sensors, trim equipment, wiring and approved software or modification status. Similar KC 140 units must not be treated as interchangeable solely because their front panels look alike.

KAP 140 operating interface and modes

The front panel provides the controls and annunciations used by the crew to engage and monitor the autopilot. The photographed unit includes dedicated AP, HDG, NAV, APR, REV, ALT and ARM controls together with UP and DN selections and a rotary control. These labels identify the functions presented by the exact unit, but actual operation remains governed by the aircraft flight manual supplement and the approved KAP 140 installation.

In a typical installation, the crew selects a lateral or vertical mode at the KC 140. The computer evaluates the selected command together with the available heading, navigation, altitude and attitude-related inputs. It then develops servo commands for the applicable control axis. The annunciation window reports selected or captured modes so that the pilot can supervise system operation. Manual trim requirements and disconnect logic remain part of the complete aircraft installation.

Flight-control signal path

A practical system chain is pilot selection and aircraft sensor input → KC 140 flight control computer → compatible roll, pitch and trim servos → aircraft control linkage. The precise connected units vary by approved installation. A KS 270-series pitch servo or KS 272C trim servo may be present in compatible BendixKing systems, but their use with a particular aircraft must be verified by complete Part Number, wiring diagram and supplemental type-certificate data.

The computer also depends on correct aircraft power, grounding, circuit protection and connector wiring. Troubleshooting should therefore consider the whole system rather than the panel alone. A mode that will not engage can be caused by an external sensor, servo, trim circuit, disconnect switch, wiring fault or installation interlock. Bench testing and return-to-service decisions require the applicable BendixKing maintenance data and approved test equipment.

Exact electrical and identification data

The original identification plate on the illustrated unit reads KC 140 Flight Control Computer and shows exact Part Number 065-00176-7703. It specifies maximum DC input of 28 V / 1.0 A or 14 V / 1.5 A. The plate also carries TSO C9c, RTCA DO-160C and DO-178B Level C references. These details are taken directly from the photographed equipment and are not transferred from another KC 140 suffix.

The photographed serial number is 4534. The face and plate images preserve the original Bendix/King markings, controls, display window, fasteners and case construction. Exact rear-connector pin assignments, mounting dimensions and clearance requirements should be taken from the installation drawing applicable to 065-00176-7703. No reliable suffix-specific dimensional values were added where the reviewed documentation did not provide them.

Serviceable supply and ordering control
