Microphone plug does not fit in the aircraft intercom panel jack
If the microphone plug on your headset does not fit in the microphone connector jack on your aircraft, try the following:
Determine if any recent changes have been made to the headset or aircraft.
If any changes or modifications have been made to either the headset or the aircraft, look into whether or not those changes could have unexpectedly caused this issue.
Connect the headset to a different panel jack or, if possible, to another aircraft.
Non-TSO equipment, worn jacks/loose connections, or incorrectly wired jacks (i.e. reversed stereo or mic / ground wires) in the aircraft can cause issues. If available, try connecting the headset to another jack in the aircraft or to jacks in a separate aircraft. If the headset works fine when connected elsewhere, the panel jack or wiring to the jack is the issue.
Plug in a different headset.
If available, connect a different headset to the aircraft to determine if the issue is related to the aircraft panel or its settings.
