I've noticed that a lot of pilots don't have any set procedure they follow when they maiden flight a new plane. I saw a nice new plane get its gear ripped off today simply because the pilot didn't know what the stall speed was for the plane. I use a "routine" that helps prevent needless accidents like this one and I was wondering how many other pilots use a set procedure and what it is. After trimming for "hands-off" flight, I immediately do several stalls by decreasing the throttle while maintaining level flight. The stalls are the very first thing I do so that no matter what else happens during the flight, I'll be comfortable landing the plane. I know the stall speed and I also try to pick out the warning signs that I'm nearing stall speed. Additionally, I have a good idea how quickly the plane bleeds off speed and how steep a glide slope it'll need if it should deadstick on me. After that, I do a few approaches. Then I go back "upstairs" and play for a bit. I don't usually have a long maiden flight, though. I like to get back down and check for things that might have loosened up.
I would like to hear from others to see what you get out of a maiden flight. Do you do something "special" that most people don't think to do? Or maybe you just have a "trademark" maneuver you do on maidens.
