N53505 - 2002 Aircraft Aircraft Registration

Both the pilot-in-command and the co-pilot allowing the aircraft to enter into an area of adverse weather (icing conditions at low [-20 degrees C] temperatures) resulting in sequential induction icing, induction filter blockage, carburetor icing and the subsequent partial loss of power in both engines followed by tree impact and collision with terrain during an emergency descent/approach. Contributing factors were icing conditions, low temperatures, night conditions and trees.
