Probable cause

The pilot's improper flare which resulted in a hard landing. Contributing to the accident was the unforcasted freezing rain that obscured the windscreen and hindered the pilot's ability to judge the height of the airplane above the runway.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Analysis

The pilot diverted to a nearby airport after he encountered unforecasted freezing rain. He made two low passes over the airport while trying to clear ice off of the windshield; however, the windshield alcohol de-ice could not keep up with the ice accumulation. The pilot stated that he had to look out of the side window during the landing and once he descended below the tree line, he was unable to accurately judge his height over the runway. He stated that this was compounded by the light color of the new concrete runway which had snow blowing across it. A hard landing resulted after which the pilot taxied the airplane to the ramp. The right wing sustained substantial damage during the landing. The pilot stated that the de-ice systems on the airplane were working, but they could not keep up with the rate of ice accumulation

Factual narrative

The pilot reported that during the flight he encountered unforecasted freezing rain. He questioned air traffic control about the weather and was told that they were not showing any precipitation. The pilot requested and received a descent to a lower altitude to stay below the clouds. The airplane's airspeed continued to decrease and the pilot informed air traffic control that he wanted to divert to a nearby airport. The pilot made two low passes over the airport while trying to clear ice off of the windshield; however, the windshield alcohol de-ice could not keep up with the ice accumulation. The pilot stated he had to look out of the side window during the landing and once he descended below the tree line, he was unable to accurately judge his height over the runway. He stated this was compounded by the light color of the new concrete runway which had snow blowing across it. A hard landing resulted after which the pilot taxied the airplane to the ramp. The right wing strut was bent and the wing was pushed into the fuselage during the landing.
