Okay, I have a bit of an odd question. I'm working with a student who had a bit of a weird situation. He took a checkride on the last day his written was valid, but because of weather the checkride was discontinued. He was working with a different instructor at the time, but I've been asked to help him study to redo his written before he finishes the checkride. I haven't been able to determine if he actually needs to complete another written or not since he only received a discontinuance even though the written is technically expired now. Does anybody know where I could dig up this information?
