There’s no such thing as an informational 337. A 337 is a 337. There’s several ways to get approved data. Not sure you guys understand the process.

Charlie, the FAA has unfortunately chosen to use the 337 form to inform them of ADS-B installations, causing much confusion and consternation in the mechanic community. They have asked for these forms to go directly to OK City and not to the local FSDO. Please refer to AFS-360_2016-03-02

Yes, Darryl Ramm is our resident ADS-B expert. He has spent many hours working on the behalf of SSA and the US gliding community helping navigate the federal maze.
