The 172 may be able to stand the G forces, but that is not the only
limitation. The carburetor only works when right side up, for example.
A barrel roll should not be a problem, executed properly, but if you
screw it up then you might have some trouble. The 172 is allowed to do
spins, but it can be hard on the instruments, knocking them back and
forth from stop to stop. For that reason some FBOs insist that spin
training be done in other airplanes.

The main reason most FBO's won't allow us to spin students is because
they invest a lot of money in gyros. I think in the "old guy days"
instrument rates were not as common and an FBO maybe had one plane for
instrument training. Today FBOs want all airplanes available for
instrument training (the IR is great money for FBOs, lots of dual and
lots of accessories to buy)

Finally, if you are the sort of person who goes out and abuses other
people's property and tries to conceal it, I suspect that most of us
would not want you renting our planes.

When gave instruction in the Decathlon the FBO broke off the "reset"
knob on the G meter so you can always see what the top and bottom G
load had been for the day on the plane.
