Duncan Aviation has launched a three-day turntime program for repairing Rockwell Collins TDR-94/TDR-94D transponders, which are widely installed in many business aircraft, especially those equipped with TCAS II systems.

“Having serviced the -003 TDR-94 units for the last several years and with more than 30 years of experience working the Rockwell Collins transponder line, these technicians have also developed a highly efficient process that will allow a one-day repair with proper scheduling,” says Kevin Miesbach, business development manager for Duncan Aviation’s avionics and instrument shop.

The repair program is available at Duncan’s Lincoln, Nebraska headquarters and at its satellite facilities in the U.S. The company can also modify earlier versions of the TDR-94 to the -500, -501 series to meet the upcoming ADS-B OUT mandate, which takes effect after midnight on Dec. 31, 2019.
