Once owned by NASCAR legend Dale Earnhardt, N21DE was in serious need of an avionics upgrade. Oasis Aviation installed:
- Dual G600 Txi 10.6" displays
- Single G600 Txi 7" display as Engine Information Monitor
- Dual GTN 750Xi GPS/Nav/Comm
- GTX 345R ADS-B in/out Transponder
- GTX 335 ADS-B in Transponder
- GFC 600 Digital Autopilot
- GI 275 as Backup Attitude Indicator
These systems were integrated and connected to existing Garmin weather radar and GDL 69 XM weather receiver.
