Avcon ISR Receives FAA Approval for Lear 60 Underwing Sensors, Pods and Target Reeling Machine

OLATHE, KANSAS, April 6, 2022, - Butler National Corporation (OTCQB: BUKS) announces that its subsidiary Avcon Industries, Inc, a leading provider of ISR and special mission solutions for aircraft, has received Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) approval for the installation of wing-mounted hard points with the carriage provisions for external stores on the Learjet Model 60 airplane.

FAA STC ST01984WI approves the installation of the Avcon ISR Solutions Learjet 60 underwing stores carriage provisions and underwing stores.  The previously-approved Avcon Hard Points have a payload capacity of up to 1000 pounds underneath each wing.  The comprehensive flight test program demonstrated underwing loads that would include the MTR-101 Reeling Machines (Tow Targets) and Special Mission Pods.  The large Lear 60 stand-up cabin provides room for up to four Special Mission consoles. The consoles may be used to control a large variety of Special Mission pods for the more complex missions needed in todays and future markets. The new aircraft capability has created significant interest from our existing customers.  The Lear 60 is an extremely capable special missions aircraft, complimentary to the already widely used and successful Lear 35/36 airplanes.

Management Comments

Christian Vila, Avcon International Sales Director said, “The Avcon Learjet 60 with the FAA-approved underwing stores approval establishes a robust new Special Mission jet platform, particularly for towing targets and carrying a larger range of NATO stores.”  Mr. Vila added: “With the aging Learjet 30 series target towing airplanes, the Avcon modified Learjet 60 will provide a special missions aircraft platform for the future that creates a new level of performance, maneuverability and technology while keeping the workhorse design. Avcon also appreciates the cooperation of its customer, Air Affairs Australia, in facilitating the project over an 18-month period.  Chris Sievers, CEO of Air Affairs Australia, added, “We’re committed to implementing hard points on the Learjet 60 to address a need in the future market and have purchased two additional Learjet 60 aircraft to modify, in order to meet our current and new customer’s needs. The payloads include the MTR-101 Reeling Machine and a large range of special mission pods, many of which Air Affairs Australia is the OEM.”  Mr. Sievers added, “I look forward to deploying our Learjet 60 aircraft with Avcon provisions for stores/hard points to provide special mission services in Australia and around the world.”
