Do NOT contact a FSDO!
They are regional offices where random FAA inspectors get assigned to phone duty and you may very well get the wrong advice as this goes waaaay passed the regular phone questions.
Call the FAA head offfice in Oklahoma and ask to speak to an inspector from Pilot Certification.
Do not be surprised that you may not evt an immediate answer as this needs to be researched. Write down the name and email of the person you’ve spoken with.
Then with any issues down the line you have a name to refer back to.
No offense to the FAA but a regional office or FSDO is nor the right place.
