Butler National gets FAA approval of AHC-3000A retrofit

Butler National Corporation (OTC Pink: BUKS) subsidiary Avcon Industries, Inc said it has received Federal Aviation Administration approval of the installation of the Rockwell Collins AHC-3000A Attitude Heading Reference System into the Learjet Model 60.

The STC retrofit package will be offered through Butler National´s subsidiary Butler Avionics, Inc.

The Learjet/Butler partnership provides Lear 60 operators with the maximum flexibility when they face AHC-85 obsolescence challenges. The FAA Supplemental Type Certificate (“STC”) approval, STC Number ST01791WI, allows retrofits of the AHC-85 computer with the AHC-3000A computer and installs the new External Compensation Unit, the ECU-3000. The STC allows the two computer AHRS system to be replaced one computer at a time (rather than both) — this offers some cost savings opportunity. Additionally, the AHC-3000A retrofit simplifies AHRS set up and calibration with most of the calibration activity completed in the cockpit — a significant improvement compared to the AHC-85.

The AHC-3000A retrofit solution is available from Butler Avionics, Inc. (Olathe, Kansas), a Rockwell Collins authorized installation/repair facility. While the AHC computer change is not exactly plug and play, the modification may be completed in 2 to 3 days. For additional STC installation information and/or an appointment to install, please call Chad Caylor at (913) 829-4606.
