Stevens Aviation Announces STC for NXT-600 Transponder
The first aircraft the Stevens Aviation Dayton avionics team STC'd with the L3 NXT-600 was a Citation 650 with a non-integrated avionics suite.

South Carolina-based Stevens Aviation has secured an approved model list (AML) STC for L3 Aviation's NXT-600 mode-S transponder. This allows the company to provide ADS-B Out compliance for several aircraft models. The first aircraft to be upgraded with the installation was a Citation 650 with a non-integrated avionics suite, and the upgrade was done at Stevens Aviation's Dayton, Ohio shop.
