Not approved?

[Cloud Basher]

PilotDAR me old mate. Good to see you are still trying to get people to agree with you that it is ok to do things that are "not approved" or "non-approved" or outside of demonstrated amounts/limits etc.

I am not sure if you are referring to me when you say I discounted your earlier reply on rolling a 172. Indeed I did say that it could be done, just that it shouldn't be.

I don't see why you are still pushing the line about wanting to go outside of what the aircraft is approved for. Can you not afford to do aeros in an aircraft approved for them. DO you HAVE to land at an airfield where the wind exceeds the demonstrated crosswind limit (and by the way it is called a limit for a reason).

For you to continually want to try and find ways around these limits, or prohibitions or non approvals leads me to the conclusion that you are a cowboy and a very dangerous pilot. If the limit on the RPM is 2700, does that mean it is ok to go to 2750 or 2800RPM and operate there? If the CHT limit is 450 degrees is it ok to go to 480 degrees? As you say the aircraft is placarded against intentional spins with flaps extended. So extrapolating unintentional spins with flaps are fine? Or maybe the manufacturer knew that you can't placard against emergencies or unintentional things....

To take this to the extreme the pilots operating handbook says nothing about not flying with 2 feet missing of the end of each wing (other than checking everything is ok on the daily inspection and your controls function correctly and freely...) so because it doesn't say that you can't fly without two feet of wing missing does that mean you would?

Mate give it up. Any pilot who actually tries and follows the rules and keeps the aircraft within its design limits and those applied by the manufacturer would never agree with you that it is ok to operate outside of those limitations in the course of a normal flight. As I said in the previous post, whilst your flight might go ok, you ARE doing damage to the aircraft and one day maybe the aircraft will fail due to the damage that you caused. Might not be your butt and it might be another 20 years from now (or it could be the next flight), the thing is WE DO NOT KNOW and if you operate outside the limits, as has been said you are a test pilot and are specifically going AGINST what the manufacturer has approved and thus invalidating all their calculations on stress, life, cycles etc. And the operating outside the limit means there is no insurance policy (literally and figuratively) and no guarantees of the aircraft being serviceable afterwards.

As for breaking the FAR’s I could care less if you break those. Just don’t go outside of what the POH says and also the INTENTION of the POH. That way if you do live through your flight, at least the next poor sod who hires the aircraft after you won’t be in for any nasty surprises.
