Airline Driver said:If you got your 1ST class Medical January 2004, then it turned to a second class medical on July 31st 2004 and then a 3rd class medical Feb 1st 2005. As of now you cannot use your commercial license let alone a CFI because you only have a 3rd class medical.
Actually to CFI and act as a PIC, you only need a 3rd class medical, so you're good to go with your 3rd class privileges. Remember, it's still a 1st class medical...but you can't use your 1st class privileges anymore.
And for the checkride in an aircraft you only need the 3rd class also.
You should be fine. Now...to use your commercial privileges? Different story.
