As has been said in all the posts, the short answer is NO. 172 is not
certified to do barrel rolls.

However I can barrel roll a 172 only pulling 1 G which puts no more
load on airframe than straight and level flight. I have thousands of
hours to back up my statement.

A corollary.

Is a 707 certified for barrel rolls? Short answer is NO.

Did a Boeing Test Pilot barrel barrel roll a 707 over the boat races
on Lake Washington without any damage to aircraft. YES.

I'm also sure Dudley can barrel roll the 172 without any problem or
exceeding any limits.

Long Long answer is don't try to B-roll the 172.

My 1971 172/Skyhawk Owneers manual shows:

Normal Cateory Maneuvers

Max pos G' = 3.8
Stalls and turns not to exceed 60 degrees of bank.

Utility Caategory Maneuvers

Max pos G's = 4.4
Chandelles
Lazy Eights
Steep Turns
Spins
Stalls (Except whip stalls)

Acrobatics that may impose high loads should not be attempted.

If kept within the normal category load limits, is 172 certified to do
barrel rolls?
