Follows Recent Upgrade Of Challenger 300

Duncan Aviation’s satellite avionics shop in Kansas City, Missouri, recently upgraded a G150 for ADS-B. As part of the upgrade, the shop sent the aircraft’s TDR-94D transponders to the avionics experts at Duncan Aviation’s Lincoln, Nebraska, location, to be upgraded.

Duncan Aviation is the only independent service facility authorized to repair, modify and convert the TDR-94D to a -501, which is required for ADS-B certification. Technicians on Duncan Aviation’s Distance Measuring Equipment (DME) bench have 40 years of combined experience on TDR-94 repairs and modifications, and support Rockwell Collins part numbers of 622-9352-002 through -008; -108; -207; -308-311; -408-411; -500-501. To date, Duncan Aviation’s DME Bench has upgraded 132 TDR-94Ds.

The DME bench upgraded the transponders quickly and the Kansas City shop installed an ADS-B Fail annunciator and the interfacing for the transponders to the GPS. The customer already had the WAAS sensors, so the Kansas City team finished the upgrade four days ahead of schedule.

The Duncan Aviation Kansas City team also recently completed a Challenger 300 in the same manner.

"Being able to send TDR-94Ds to our team in Lincoln gives us a huge advantage in being able to complete ADS-B installations very quickly,” says Jeff Aman, the Kansas City Shop Manager. “Customers fly away extremely happy knowing that we saved them unproductive downtime."
