barrel roll in 172

That's good, but I've heard of one case where the ailerons
moved together up and down, not differentially. Direct lift
control, but is right up or down? I don't that airplane
actual tried to take-off.

If you box the control you can check for full and
unrestricted travel for elevator and ailerons as well as
correct rigging. I have seen wire bundles get loose and
block control travel and you might see the ailerons move
correctly, but you might not have full travel of the
elevator.

This is a killer, take off with engine failure, you can have
a good chance to land without any damage. Have the controls
locked, blocked or reversed and you're a passenger in a
missile. The WSU football team DC3 tried to take-off with
the gust locks installed on the tail, a C310 in Tulsa back
in the early 70s took off with the controls reversed and
immediately rolled into a smoking fireball. These are pilot
error. The mechanic made a mistake, but the pilot has to
check and verify... FREE and CORRECT. Test flying is any
first flight after any work is done to the airplane, from a
tire or oil change to a control replacement.
