Certified? No.
Possible? Yes, but you will finish much lower than where you started.

Don't encourage that type of behavior with a yes. If he had to ask, he is
probably not a competent aerobatic pilot, and a blown barrel roll could
stall the plane, or overstress it, so it fails then, or later.

I'll bet he is not going to wear a parachute, either, which is required.

The answer to rolling a normal category plane should be no, always.

We don't want his, or someone else's blood on our hands.

I am wondering why, if one may spin a 172, why one may not roll a 172 ...

Because Cessna didn't make it in the aerobatic category.

The issue is recovery from a botched barrel roll, such as in
inverted stall followed by a high speed dive and too strong
a pull on recovery.


For what maximum negative G load is the a C-172 certified in Utility
Category? For what absolute maximum negative G load is the C-172
designed?
