The NTSB's narrative final · quoted from the NTSB record
The pilot, who was executing a global positioning system approach to a non-controlled airport, saw a snowplow clearing snow from the runway as he broke out of the overcast in a light snow shower. Soon after the pilot spotted the snowplow, it exited the runway, and the pilot continued his approach/landing sequence. After touchdown, the airplane encountered an area of ice and slush on the runway and began to slide. The pilot stated that he should have initiated a go-around, but the airplane was never sufficiently realigned with the runway so he could safely apply go-around power. As the pilot continued his efforts to realign the airplane with the runway, the airplane departed the side of the runway and impacted a natural gas line warning sign. The impact with the sign resulted in a tear in the stressed skin of the fuselage that exceeded eight inches in length. The pilot did not report any mechanical malfunction during the accident sequence.
