KA 51B vertical-mount compass slaving accessory 071-1242-00

071-1242-00 is the exact Part Number for this BendixKing / Honeywell KA 51B vertical-mount compass slaving accessory. The unit provides manual slaving and free-gyro controls for a compatible KCS 55A compass system. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every KA 51B version or a visually similar member of the same family.

The source record and image filename identify Part Number 071-1242-00 with serial reference 15452. The visible 14 V lighting caution marking supports the documented lighting configuration. The unit is offered serviceable with EASA Form 1 and is described as TSO-approved. Values belonging to 28 V KA 51B suffixes are not transferred to this version. 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 this KA 51B configuration as a slaving accessory for the KCS 55A system. Its FREE, clockwise and counter-clockwise controls support compass-system slaving functions, while the connected compass equipment performs sensing, processing and heading indication. This -00 version is specifically identified as a vertical-mount, 14 V white-lighting configuration. 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 KA 51B 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 unit is intended for an approved KCS 55A installation and depends on compatible compass-system equipment, aircraft wiring, 14 V lighting circuit, correct vertical mounting, connector arrangement and panel provisions. Similar KA 51B versions with different suffixes, mounting orientation or lighting voltage must not be treated as interchangeable without approved data. 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 071-1242-00 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 071-1242-00

The suffix in 071-1242-00 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.

Serviceable condition, ordering and support

This 071-1242-00 KA 51B is offered in Serviceable 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 071-1242-00, model KA 51B, 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.
