That's an ARC/Cessna RT359A that's tagged inoperative. When one fails we say move onto something digital that doesn't have a cavity tube.

Now that you’ve equipped for the ADS-B mandate, you’ll need to make sure the transponder remains in good working order. Ones that aren’t are on the FAA’s enforcement list.

There are plenty of aircraft for sale that need transponder (and ADS-B) upgrades, and as we’ve advised for years, the age and health of the existing unit should be a factor when selecting the right ADS-B Out solution. It’s simple—an ADS-B transponder is the best solution for aircraft with vintage models—and that’s still the advice moving forward.
