BendixKing KFS 586A ADF control 071-1284-09

071-1284-09 is the exact Part Number for this BendixKing KFS 586A automatic direction finder control unit. It is the cockpit interface used to select ADF frequencies and operating modes in a compatible KDF 806 installation. The compact panel combines a frequency display, channel selection, tuning control, mode selection and volume or power control, allowing the crew to manage the receiver without accessing the remotely installed electronics.

The KFS 586A is a control head, not a complete direction finder by itself. It does not receive the radio signal or calculate bearing independently. A normal functional path is crew input at the KFS 586A, command transfer through the approved aircraft wiring, frequency and mode processing in the compatible KDF 806 receiver, and bearing presentation on the connected cockpit indicator. Antenna, receiver, indicator and installation wiring remain separate associated equipment unless a quotation expressly includes them.

Frequency selection and stored-channel operation

Published KFS 586A data identify a tuning range from 190 kHz to 1799 kHz in 1 kHz increments. The microprocessor-controlled design uses a gas-discharge display and nonvolatile frequency storage so selected values can be retained when electrical power is removed. The CHAN control recalls stored channels, while the main tuning control changes the displayed frequency. The exact number of usable memories and any optional 2182 kHz function depend on the approved receiver and installation configuration.

The front panel also provides standby indication and mode selection. These controls support efficient frequency management during flight, but they do not establish aircraft eligibility or receiver compatibility by appearance alone. The connected KDF 806 configuration, control wiring and aircraft-approved equipment list must agree with the exact control-head suffix. When replacing an older KFS 586, maintenance personnel should verify the installation data rather than assuming that every KFS 586A suffix is a direct substitute.

Exact -09 lighting and panel configuration

The 071-1284-09 configuration is documented with a black bezel, 28-volt lighting, a standard lens and Mode, On/Off and Volume controls. Other KFS 586A suffixes use different bezel colors, lighting voltages, lens constructions or control combinations. Those differences can be easy to miss in a general product photograph, which is why the complete 071-1284-09 number should appear on the purchase order, receiving record and installation approval.

Published physical data for the KFS 586A give an approximate size of 2.093 inches wide, 2.250 inches high and 7.375 inches long, with a weight of about 0.68 pounds. The documented operating temperature range is approximately -20 °C to +55 °C. TSO C41c Class A and the listed environmental category apply to the documented design. Final mounting clearance, connector access, cooling and lighting connections must still be checked against the current installation manual.

KDF 806 integration and maintenance checks

In a compatible ADF system, the KFS 586A supplies frequency and operating commands to the KDF 806 receiver. The receiver works with the installed ADF antenna system and provides bearing information to an approved indicator or integrated display. A defect elsewhere in that chain can resemble a control-head fault, so troubleshooting should include power, grounds, data lines, antenna circuits, receiver operation and indication before the panel is removed.

Receiving inspection should compare the full Part Number, serial number, bezel, lens, lighting marks, connector and control layout with the ordered configuration. A bench test should confirm display readability, frequency entry, channel recall, mode selection, power and volume controls and communication with compatible test equipment. Installation and return-to-service work must follow the applicable KDF 806 and KFS 586/586A maintenance data rather than a generic pinout.

Serviceable supply and ordering information

This 071-1284-09 KFS 586A is offered in Serviceable condition from partner stock with a six-month warranty. The studio image shows the operational faceplate, while the authentic gallery image preserves the photographed housing, connector area and original identification details. A serial number visible in a photograph documents the reference unit only and does not guarantee allocation of that same serial-numbered component unless confirmed in the quotation.

For an inquiry, specify Part Number 071-1284-09, model KFS 586A, aircraft type, KDF 806 receiver configuration, required lighting voltage, desired documentation and quantity. Related ADF, navigation and communication equipment can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Related products may operate in one avionics installation but are not automatically interchangeable, and any substitution requires an approved configuration review.
