What do you mean? What sudden unpleasant consequences are you referring to?

A departure from controlled flight, such as a stall or spin, or in
some cases simply slips or other uncoordinated movements that may make
passengers queasy.

Are you claiming that turning a plane using only the rudder kills?

Apparently so, in some cases, based on what I've read. The stuff I'm
reading claims that it's a common mistake in phases such as landings,
and sometimes it kills the pilot.
