I have a friend who recently busted an internal proficiency check at the school he works for. Sounds like it was just a proficiency check that all the instructors there have to do. He’s nervous it will be a sticking point later in his career. I told him it’s probably not a big deal, but I don’t actually know...I’m assuming check ride failures for certificates and ratings hold significantly more weight than stage checks, right? At least at my school, if you were going to fail a ride, you wanted to get it over with on a stage check.
