BendixKing KFS 564A control 071-1283-38

071-1283-38 is the exact Part Number of this BendixKing KFS 564A navigation control head. The panel provides active and standby navigation-frequency selection for compatible remote KNR 634 and KNR 634A navigation receivers. Its dual-line display, standby transfer switch, volume and power control, concentric channel selector and annunciator give the crew a compact interface to the remote NAV equipment.

The KFS 564A is not a complete VOR, localizer or glideslope receiver by itself. It sends selections to the connected remote receiver, while navigation signals and indications continue through the approved aircraft interfaces. The complete -38 suffix is important because KFS 564A variants differ in lighting voltage, faceplate colour, display construction and installed controls.

Active and standby navigation selection

The dual-line display presents active and standby selections so a frequency can be prepared before it is transferred into use. The large concentric knob changes the selected digits, and the SBY switch exchanges the standby and active values. The VOL / OFF control provides the documented on/off and audio-level functions for the compatible installation.

A typical functional path is KFS 564A crew selection → compatible KNR 634 or KNR 634A remote NAV receiver → approved navigation indicator, EFIS or aircraft system. The controller is therefore associated with the remote receiver and display equipment but is not interchangeable with either. The receiver suffix, navigation outputs, annunciation and aircraft wiring must all be verified before installation. This separation also helps maintenance personnel isolate a tuning-control fault from a receiver, antenna, indicator or aircraft-interface fault during approved troubleshooting.

115 VAC NVG configuration

Exact-part repair documentation identifies 071-1283-38 as a KFS 564A NAV control with 115 VAC lighting and NVG-compatible display configuration. The photographed unit has a black faceplate and carries a visible 115 V lighting caution label. The lighting rating belongs to the panel illumination circuit and should not be described as the operating supply of the connected KNR receiver.

NVG compatibility and lighting voltage are suffix-specific. A similar black KFS 564A with 28 V lighting or a conventional display cannot be treated as a direct replacement based on appearance. Maintenance personnel should verify the full Part Number, display layer, dimming circuit, faceplate, modification status, software configuration, connectors and aircraft approval before accepting a substitute.

Identification, weight and maintenance checks

The authentic side plate identifies KFS 564A NAV CONTROL, P/N 071-1283-38 and serial number 10442 on the photographed unit. It states a weight of 1.1 lb, approximately 0.5 kg. These direct plate values provide receiving-inspection references for the exact suffix without transferring specifications from a different KFS 564A version.

Bench testing should confirm both display lines, digit selection, active/standby transfer, volume and OFF functions, annunciation, NVG lighting and communication with the remote NAV receiver. The rear connectors, mounting structure and case should be inspected for damage or unauthorised modification. Exact dimensions, cut-out requirements, connector pin assignments and test tolerances must be taken from approved KFS 564A / KNR 634 technical data.

Overhauled supply and ordering information

This 071-1283-38 KFS 564A is offered in Overhauled condition from partner stock with a six-month warranty.
