Butler National Announces Learjet 35/36 and Learjet 24/25 STC for ADS-B Compliance

OLATHE, Kan., Aug. 3, 2016

The FAA STC approval, STC Number ST02230SE, provides for an ADS-B(Out) solution by retrofit of the two existing transponders with the Garmin GTX-345R [ADS-B(In) and (Out)] or GTX-335R [ADS-B(Out)] transponders and installation of the GTN 625, 725, 650 or 750 Navigator/GPS/SBAS WAAS for real time aircraft location.   The Learjet 20 and 30 Series offering expands the Butler Learjet Model 60 ADS-B offering (STC ST02455SE).

The ADS-B equipment mandate in the United States is set for January 1, 2020.  The Butler National ADS-B solutions are now available for the Learjet 60, Learjet 35/36 and the Learjet 24/25 series airplanes.  The approved installations allow equipment variation for multiple levels of functionality for the operator in addition to ADS-B(Out) compliance.  The Butler National Solution offers a cost-effective price point that coincides with functionality.  The GTN installation may also provide full WAAS/LPV coupled approach capability as well as roll-steering guidance to the autopilot.  The GTX-345R installation offers ADS-B(In) functionality on applications for portable electronic devices, such as the iPad.

Mr. Clark Stewart, President and Chief Executive Officer of Butler National Corporation commented, "The Butler National ADS-B(Out) STC solutions offer very useful upgrades for navigation and communication in addition to ADS-B(Out) compliance.  I am confident that operators will also find the ADS-B(In) information very useful with the GTX-345R installation."     

Mr. Stewart added: "Butler National is pleased to offer this Lear 20 and 30 Series ADS-B(Out) Solution in addition to the Butler National Lear 60 ADS-B(Out) Solution.  We have taken on the opportunity to allow Learjet operators compliance with the ADS-B(Out) requirements well in advance of the 2020 deadline.  We have received considerable operator interest in the solutions and have scheduled installation slots into late 2016.  We are moving forward with adding the Learjet Model 31/31A and Learjet Model 55 to the STC as well as offering TCAS II-compatible solutions.  With our subsidiary, Avcon Industries, we offer the flexibility of combining aircraft maintenance, such as A or B inspections, along with the ADS-B retrofit.  Butler continues its efforts to be a 'go-to source' for legacy Learjet Solutions.  This ADS-B STC solution is one more example of the Butler commitment to the Learjet aircraft."
