We recently developed a TDR-94/TDR-94D Quick Turn Team 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.
We have been authorized by Rockwell Collins 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. We also modify earlier transponders to the -500-501 series, which will meet the ADS-B Out mandate when the unit is properly installed and certified.
