Event Description
During an ILS approach, the pilot reported that the airplane encountered freezing rain that was transitioning to snow as it broke out of the clouds at 600 feet above ground level. The pilot stated that the aircraft had accumulated approximately 3/8 to 1/2 inch of ice on its airframe. The landing was conducted at dusk on an ice-covered runway.
Pilot Observations
The pilot noted that the winds were from a left quartering tailwind at 10 knots. He landed in a slight crab to compensate for the crosswind component. The windshield was covered with ice, except for a clear area measuring about 8 by 11 inches through which the pilot could maintain visibility.
Landing and Aftermath
According to the pilot, the airplane initially touched down on its left main landing gear. As the nose gear and right main landing gear contacted the runway, the left main gear tire rolled off its wheel. Subsequently, both the right main and nose landing gear collapsed. The pilot attributed the gear collapse to the conditions but no official causal statement is provided.
