concur with Jim's explanation. the aircraft appears to still be
overloaded, and unable to take advantage of ETL at this altitude. as it
moved over the small valley, it lost the benefit of ground effect, sank,
and likely had a tail rotor strike.

guessing the altitude is somewhere between 1000 and 3000 meters, but
unsure of the temperature. humidity is likely low, but high and heavy
are the two key parameters in this equation, with hot and humid playing
lesser roles.

Duh! This video kind of makes the tail rotor question pointless. It is
so obvious the the impact of the tail rotor with the ice caused the
damage to the tail rotor. So I guess the tail rotor was "broke away"
which then contributed to the crash. Looks like what actually happened
may be the helicopter left the sanctity of ground effect prior to
gaining ETL


Hi,

THIS IS TOP URGENT!..

I have a movie with a helicopter accident. The helicopter crew claims
that the
