I got this response from the school/rental FTO I use in CA. Basically it seems if you have the quals already you are ok, if not you are stuffed!
Hi Julian,
The situation at this time is anyone with a comp FAA cert is OK to continue.
They are not issuing new ones for a while.
The next problem is we can not change a cert, ie add a rating IFR or multi.
So I am not sure what you have but if you need to add the IR we would have
to do the PPL and IR flight test.
If you already have these quals then you are good to keep using them.
This was implemented very quickly we do not know how long it is in effect,
nor does anyone at the FAA that I have talked to. I will keep you informed
of any changes that I come across.
