One of my colleagues at Oxford forgot to put the gear down on his IR a few years back. That`s always a good one to remember!!!
Funnily enough he still managed to get a partial pass????
I can`t recall whether or not they clipped the props or not but it was a common occurence as a few of the examiners liked to pull the CBs to stop annoying horns going off.
Anyhow, he happily drives 757s for a major UK charter company now
On a serious note though. One thing that does look sloppy on an IR is people who don`t correct themselves when they get a little high or low. If you`re supposed to be flying at 3000' for example DO IT. Don`t accept 2900' or 3100' and maintain it. If you get a little out correct yourself.
This is especially important when attending SIM rides for job interviews.
