NavWorx ADSB shut down

[underfire]

The FAA wants to fine the now-shuttered NavWorx $3.7 million for allegedly altering its ADS-B transmitters to hide the fact that they used a non-compliant GPS chip. The agency says in a news release that NavWorx knew the chip didn’t meet standards tightened in 2015 for system integrity level (SIL) and rather than use a conforming chip the company changed some software in the ADS-600B units to emit a code that falsely indicated the chip met the standard. The FAA says the company advertised and sold the devices as being compliant with the 2020 ADS-B mandate when the substandard chip made the transmitters ineligible. Last week the company abruptly closed its doors and seemed to try to shift responsibility to the company that makes the GPS chip.
