KFS 576 digital transponder control unit 071-1192-08

071-1192-08 is the exact Part Number for this BendixKing / Honeywell KFS 576 digital transponder control unit. The unit provides cockpit mode and code control for a compatible KXP 756 transponder installation. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every KFS 576 version or a visually similar member of the same family.

The exact source record identifies Part Number 071-1192-08 as a black-bezel KFS 576 digital control for the KXP 756 transponder. It specifies 28 V panel lighting, single-transponder selection, overhauled condition and EASA Form 1. The photographed unit is identified with serial number 3373. The identification information is important because voltage, lighting, software, hardware options, certification and connector configuration can differ across related versions. The complete Part Number and the approved technical record must be checked together before purchase or installation.

Operational role and system function

The KFS 576 is the crew-facing control unit for the associated KXP 756 transponder. Its front-panel controls provide single-transponder selection and the normal cockpit functions indicated on the panel, while the connected transponder equipment performs transmission and reply processing. The control unit cannot operate as a complete transponder by itself. In service, the unit depends on the integrity of its associated sensors, antennas, transceivers, control panels, displays, data buses, wiring, power and grounding. A reported fault at the unit can therefore originate elsewhere in the connected chain, and troubleshooting should follow the approved aircraft and equipment procedures.

The practical role of KFS 576 is to perform its defined function while exchanging required signals with compatible equipment. It cannot replace missing system components and should not be evaluated as an isolated consumer device. Controls or connectors visible in photographs do not prove that every possible function is enabled in a particular aircraft installation.

Installation and connected equipment

The documented connected unit is the KXP 756 transponder. An approved installation also depends on the applicable transponder rack, antenna and coaxial cable, altitude-data source, aircraft wiring, panel-lighting circuit, power protection and any encoder or surveillance interfaces required by the aircraft configuration. A rack, backplate, connector kit, antenna, wiring, cooling hardware or other accessories are not assumed to be included unless they are expressly listed in the quotation. Similar panel dimensions or family names do not prove electrical or approval compatibility.

Before installation, technicians should compare 071-1192-08 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. Panel space, mounting depth, connector keying, pin allocation, circuit protection, lighting, ventilation, data format and configuration settings all require confirmation. Any substitution must be supported by approved data.

Configuration checks for 071-1192-08

The suffix in 071-1192-08 is part of the product identity. Software level, modification status, database requirements, embedded options, voltage and certification can affect compatibility even when two units look alike. These checks are especially important in aircraft that have accumulated supplemental approvals, avionics upgrades or wiring changes over time.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. Functional testing should use the approved bench procedure for the exact model and suffix. Installation and return to service remain the responsibility of appropriately authorized personnel.

Overhauled condition, ordering and support

This 071-1192-08 KFS 576 is offered in Overhauled condition from partner stock with a six-month warranty. Partner stock should be reconfirmed at quotation because allocation can change. The available serial number, current test status and release documentation for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 071-1192-08, model KFS 576, required quantity, destination and documentation requirements. Including the aircraft type and removed-unit Part Number helps prevent configuration errors. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown there are related catalog positions, not interchangeable replacements unless approved technical data explicitly says so.
