An/arc-190. Had hf 1 and 2 coupler fault pop up mid flight. Would rx but no tx or tune tone. Repressurized #1 coupler and both started started working again. Didn't make sense to me why #2 would start working other than the rf interlock relays are the only thing that shares a connection (i believe). However, sys would work fine until the next day, and the same problem returns on both system. Repressurized #1 again and both starts working. Anyone seen due to hf 1 fail, to cauaes #2 to fail as well? Could this coupler be losing pressure over night? Dont have any parts so im trying to narrow it down

We had an incident where one of the propellers on an aircraft went into an uncommanded reverse. Has anyone experienced this? It is the first time in (our) history that something like this has happened. It is still under investigation and is of huge concern to us because this incident happened on a pre-take-off run. Any suggestions/help will be appreciated!
