Just a little perspective here. Nearly 15 years ago, I failed my private, comm, and CFII, All with the same examiner. They were legit busts, but he was a tough examiner.

All these years later I have 4 transport category PIC type ratings. I've been a 121 captain on 3 of those planes. I have more than enough 121 PIC time. I'm a sim instructor at my airline. I've taken more than a decade worth of 121 recurrent check rides and line checks and fed observations. I've never had a single 121 failure in all of those years. In fact, I've never had to retrain a single event on any of those check rides. Never needed an extra sim session. Even debrief items are rare.

Why should I still be penalized for those three failures 15 years ago?
