Content Body

The FAA has issued supplemental type certificate approval to Butler National for ADS-B OUT upgrades for the Learjet 24/25 and 35/36. The 24/25 upgrade is an expansion of Butler’s existing Learjet 60 ADS-B upgrade.

The STCs are for replacement of the existing transponders with Garmin’s GTX 345R (ADS-B OUT and IN) or GTX 335R (ADS-B OUT only) along with a GTN series touchscreen navigator to provide the required position source. The GTN can also provide WAAS LPV coupled approach capability and roll steering guidance to the autopilot. The GTX-345R delivers ADS-B IN information to mobile devices.

Butler plans to develop ADS-B STCs for the Learjet 31/31A and 55 and to offer TCAS-compatible solutions. The company’s avionics shop is already booked through late this year. “With our subsidiary, Avcon Industries,” said Clark Stewart, president and CEO, “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."
