Duncan Aviation authorized to service Rockwell Collins TDR-94/TDR-94D transponders

Rockwell Collins recently approved Duncan Aviation as an authorized service provider for repair, service and modification of its TDR-94 and TDR-94D transponders. The Rockwell Collins TDR-94D transponder is a solid-state, crystal-controlled receiver/transmitter specifically designed for TCAS-II-equipped business aircraft. The units can be upgraded and when professionally installed and certified will meet the upcoming ADS-B mandate for 2020. 

“Duncan Aviation has been servicing the -003 TDR-94 transponders for several years and is able to offer customers excellent turntimes,” says Kevin Miesbach, Components/OEM New Business Development Manager with Duncan Aviation. “We can offer the repair, installations and upgrade modifications of these units at our main facility in Lincoln, Nebraska, as well as through our satellite avionics facilities located throughout the United States.” 

The new agreement allows Duncan Aviation to repair and service transponders with the Rockwell Collins part numbers of 622-9352-002 through -008; -108; -207; -308-311; -408-411; -500-501 and 622-9210-002 through -008; -108; -207; -308-311; -408-411; -500-501. The company will also be able to modify earlier transponders to the -500-501 series, which will meet the ADS-B mandate when properly installed and certified. Duncan Aviation’s authorization is for transponders from aircraft in North and South America, Europe, the Middle East and Africa. The agreement with Rockwell Collins is exclusive and Duncan Aviation will be the only non-OEM facility authorized for the repair and upgrade. 

“We are pleased to work with Rockwell Collins on this agreement and look forward to supporting our mutual customers,” Miesbach says. “Duncan Aviation and Rockwell Collins have a longstanding relationship based on trust and collaboration in an effort to provide the highest level of quality and customer service to operators. One of the benefits for customers is that these additional capabilities allow Duncan Aviation installation facilities to support customers with the entire modification process of these units from component modification to system installation and certification.” 

Duncan Aviation installations can be performed at the three main full-service locations in Lincoln, Neb., Battle Creek, Mich., Provo, Utah as well as at the 20+ satellite avionics facilities Duncan Aviation has located at high-traffic corporate jet airports throughout the United States.
