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

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?

Acrobatics that may impose high loads should not be attempted.
