Narrative:
The aircraft was on short finals (at 400 feet agl, 35deg flaps) when it suddenly pitched down, entering a steep descent. It partially recovered before impact with a dirt hill, 500 feet short of the Runway 28. Ice accretion on the horizontal stabilizer leading edge was found (0,50-0,75 inch).

PROBABLE CAUSE: "A loss of control due to the improper in-flight decisions by the crew and the undetected accumulation of ice on the leading edge of the horizontal stabilizer, during flight in a forward centre of gravity condition and exacerbated by the extension of full landing flaps. "
