10 months ago I voluntarily stopped flying and started the HIMS path toward a SI. My medical has never been revoked, suspended, or denied. My HIMS AME has performed a first class medical exam. I passed the first class medical however it was then deferred, pending the FAA approval process. The Doctor says I am good to fly but the FAA has to review my file and then issue a SI. My question is, can I now excercise the privileges of a sport pilot while I wait for the tedious approval process? I realize that if my application is denied, that I would be excluded from all flying. The way I am reading the rules is that I had a medical condition (disease) and I pulled myself from flying. Then I sought treatment and a doctors opinion and found fit to fly however I don't have a medical so I would only be able to excercise sport pilot privileges.??
