Probable cause

The pilot's failure to maintain a proper glidepath while on short final approach. A factor in the accident was the dark night lighting conditions which may have affected the pilot's perceptual awareness of the airport environment and the cues for a proper visual approach slope guidance.

Analysis

The pilot said that he turned on a one to one and one half mile base for runway 35 and keyed his microphone to activate the pilot controlled lighting system. The pilot said that on final approach he noticed that the VASI lights were not operating. He further reported that everything seemed fine on final approach until about 200 feet AGL when he said he became aware of a loss in altitude. The pilot stated that he began applying power to correct the situation and then observed a tree top pass the copilots window. Examination of the aircraft revealed that the right wing had collided with the tree. An FAA inspector stated that the tree contacted by the aircraft was about 30 feet tall and located about 600 feet from the approach end of the runway.
