First post here, wanting to learn. I have read that if one goes for a 1st 2nd or 3rd class medical and is denied then that person is not eligible to receive their sport pilot either. If someone already has their sport pilot license and they attempt and fail a FAA medical, then is their sport pilot revoked at that point? Also, can a sport pilot fly a Cessna 140,150 or 152? If it’s under the designated weight and since they are all single propeller aircraft? I would like to learn to fly a seaplane one day. Thank you
