Those aircraft known to be "bulletproof" are never found in RA categories.
Actually, i would put the Jabiru airframe firmly in the bullet-proof category. those things are unbreakable, seen them flown into forests, shipping containers, and thrown at numerous runways breaking the wheel off them, and they all end up back in the air in short time. as for the reasons they land in trees/shipping containers/ditches etc, is another story entirely.
