Sultan,
At least the 92 can "autorotate" to a landing....something your favorite bird cannot do at all. Your favorite machine cannot survive dual engine failure....or loss of the last engine when in the helicopter mode below 1600 feet AGL.....or AVRS below that same approximate altitude. Bell admits to those problems.
Perhaps you might spend some time worrying about that rather than wasting our time suggesting the Sikorsky Products cannot survive a tail rotor failure which you do without any corroborating source material.
