Really unlikely. When you're on the ground, the wings aren't holding the
plane up. The landing gear is.

Last time I looked the main gear on Jay's airplane was attached to the
wing. The spar is still taking the load.

Oops! Thought he drove a 172...


Unless you're really competent with acro, even something as innocent as a
chandelle or lazy 8, spiral or spin can quickly get out of hand and
stress
the airframe.

You're kidding right?! I've done acro, but I certainly don't consider
myself "competent" (which frankly, is why I've never rolled the Cessna's
I fly). I am quite capable of doing lazy 8s or chandelles without
"getting out of hand".

IMO a private pilot should be able to do a lazy 8 or chandelle without
losing control of the airplane. They are simply climbing and/or
descending turns done at moderate bank angles. The chandelle is the
only one that "pushes" at all since you get very close to stall at the
finish.

Should be? Sure. Is? Nope. I've taken lots of people through this stuff
and most, pilots and even some non-pilots are fine with them. But a few,
who may have only done them many years before when getting their ticket,
hesitate on the recovery. The airspeed winds up and they overreact on the
pullout. If you don't believe this happens, get the proper qualifications
and try it on a bunch of people. Preferably in something designed to handle
it. Or ask an acro instructor. The one who taught me worked for Bombardier
and used my plane to teach an emergency maneuvers course to Bombardier
pilots. He said one of the first thing he did was roll inverted to a +1G
dive and ask them to recover. He said many tried to pull out of it. That,
in anything not designed for acro can be fatal. You may have better
instincts or training or both. But many, many people don't. Again, the
post by DH says it as well as I've ever read.
