KNR 634 airborne navigation receiver 066-1078-00

066-1078-00 is the exact Part Number for this BendixKing / Honeywell KNR 634 airborne navigation receiver. The unit receives and processes compatible radio-navigation signals for use by the aircraft navigation and indication system. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every KNR 634 version or a visually similar member of the same family.

The exact photographed unit is identified as KNR 634, Part Number 066-1078-00, serial number 5414. The partner record describes it as TSO-approved and supplied in overhauled condition. Publicly available data for other KNR variants must not be transferred to this suffix without the applicable BendixKing maintenance or installation manual. 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 source listing identifies the KNR 634 as a navigation receiver used with the KFS 564 control unit. The front panel visible on this exact unit carries NAV/REC, marker-beacon and glideslope-related connections, showing that it belongs within a larger radio-navigation installation rather than operating as a self-contained cockpit indicator. 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 KNR 634 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

A complete installation requires the applicable KFS 564 control, approved antennas and couplers, aircraft power and ground, wiring to compatible indicators, and any marker-beacon or glideslope interfaces specified by the aircraft design. Connector allocation, rack, cable terminations and signal levels must be checked against the approved data for 066-1078-00. 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 066-1078-00 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 066-1078-00

The suffix in 066-1078-00 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 066-1078-00 KNR 634 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 066-1078-00, model KNR 634, 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.
