Beschrijving:
Piedmont flight 230 was on an ILS localizer approach to Charleston-Kanawha County Airport (CRW) runway 23 when it struck trees 360 feet from the runway threshold. The aircraft continued and struck up sloping terrain (+30deg) 250 feet short in a 4-5deg nose down attitude, slightly left wing down. The Fairchild continued up the hill and on to the airport, coming to rest 6 feet beyond the threshold and 50 feet from the right edge of the runway.
A layer of dense fog (about 150 feet thick) was obscuring the threshold and about half of the approach lights. Visual conditions existed outside the fog area.

Probable Cause:

PROBABLE CAUSE: "An unrecognized loss of altitude orientation during the final portion of an approach into shallow, dense fog. The disorientation was caused by a rapid reduction in the ground guidance segment available to the pilot at a point beyond which a go-around could not be successfully effected."
