Industry Segmentation

Current Activities - The Company focuses on two primary activities, Professional Services and Aerospace Products.

Aerospace Products:

Aircraft Modifications principally includes the modification of customer and company owned business-size aircraft from passenger to freighter configuration, addition of aerial photography capability, and stability enhancing modifications for Learjet, Beechcraft, Cessna, and Dassault Falcon aircraft along with other specialized modifications. We provide these services through our subsidiary, Avcon Industries, Inc. ("Aircraft Modifications" or "Avcon").

Avionics principally includes the manufacture, sale, and service of airborne electronic switching units used in DC-9, DC-10, DC-9/80, MD-80, MD-90, and the KC-10 aircraft, Transient Suppression Devices (TSDs) for fuel tank protection on Boeing Classic 737 and 747 aircraft, and other Classic aircraft using a capacitance fuel quantity indicating system ("FQIS"), airborne electronics upgrades for classic weapon control systems used on military aircraft and vehicles, and consulting services with airlines and equipment manufacturers regarding fuel system safety requirements. We provide the products through our subsidiary, Butler National Corporation - Tempe, Arizona and the services through Butler National Corporation - Olathe, Kansas ("Avionics", "Classic Aviation Products", "Safety Products", or "Switching Units").

In September 2010 we expanded this division by the acquisition of Kings Avionics, Inc. The acquisition of Kings Avionics allowed us to transition into the new technology available in avionics. Kings Avionics sells, installs and repairs avionics equipment (airplane radio equipment and flight control systems). These systems are flight display systems which include intuitive touchscreen controls with large display to give users unprecedented access to high-resolution terrain mapping, graphical flight planning, geo-referenced charting, traffic display, satellite weather and much more. Kings Avionics is also recognized nationwide for its troubleshooting and repair work particularly on autopilot systems.

Professional Services:

Butler National Services, Inc. ("BNSI" or "BNS") provides monitoring and related repair services of water and wastewater remote pumping stations through electronic surveillance for municipalities and the private sector.

BCS Design, Inc. provides licensed architectural services. These services include commercial and industrial building design.

Butler National Service Corporation ("BNSC") provides management services to the Boot Hill Casino, a "state owned casino" and to The Stables, an "Indian owned casino".
