JET Products and Services

Butler National Corporation has acquired the JET Learjet Legacy Product line which involves the Learjet 20, 30 and 50 Series Aircraft. Product services are currently in a transitional phase from L-3 Communications to Butler National and Butler Avionics. Some units have already transitioned to Butler Avionics, which will provide service (repair and overhaul). Some of the products are still being serviced by L-3. Access to the list of products by part number and where to have them serviced are listed below. This list will be periodically updated as products are transferred to Butler Avionics.
