Statement of Work DC-8 ADS-B Upgrade

NASA AFRC

The NASA DC-8 Project requires an upgrade to our current Rockwell-Collins TDR-94D Series Level 1 ADS-B Transponders. NASA currently has two Level 1 ADS-B Transponders with P/N 622-9210-108.

NASA requires two ADS-B Level 2 compliant units compatible with our currently installed Rockwell- Collins TCAS II system (TCAS II Transmitter Ver. 7.1 TTR-4000 P/N 822-1294-032). The Rockwell- Collins TDR-94D Series Level 2 ADS-B Transponder compatible to our DC-8 configuration is P/N 622- 9210-501.

NASA desires to obtain two compatible Level 2 ADS-B Transponders. NASA is looking to purchase Rockwell Collins P/N 622-9210-501 or an equivalent. Purchase options include:

Option1: Purchase of Rockwell Collins P/N 622-9210-501 or equivalent

Option 2: Purchase of Rockwell Collins P/N 622-9210-501 or equivalent with exchange credit for turn-in of Rockwell Collins P/N 622-9210-108

NASA requires Rockwell Collins P/N 622-9210-501 or equivalent by May 8. If option 2 is selected and P/N 622-9210-501 is received by May 8, NASA will ship Rockwell Collins P/N 622-9210-108 to the vendor within 20 days of receiving the unit. If P/N 622-9210-501 arrives after May 8, it may take up to two months before we can ship P/N 622-9210-108 back to the vendor.
