The Duncan Aviation avionics instrument shop is now able to provide operators with TDR-94/TDR-94D transponder service that includes same-day evaluation and three-day turntimes, with AOG options available when needed.
Our technicians, having serviced the -003 TDR-94 units for the last several years, have developed a very efficient repair process that will even allow a one-day repair, provided the following steps are taken by the operator:
800.562.6377 or 402.475.2611
This gives us time to ensure we have parts on hand when the transponder arrives.

We offer the repair and service of these units at our main avionics instrument shop in Lincoln, Nebraska, as well as through our satellite avionics facilities located throughout the United States.
We are also able to modify earlier transponders to the -500-501 series, which will meet the ADS-B mandate for 2020 when the unit is properly installed and certified.
