Probable cause
The pilot's failure to correctly identify the runway environment during an instrument approach at night in instrument meteorological conditions because he mistook building lights for runway lights, which resulted in landing short of the runway.
Findings · 8
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.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that, while conducting an instrument approach at night in instrument meteorological conditions, about 50 ft above the decision altitude of 921 ft, he mistook building lights for runway lights. He inadvertently touched down the airplane in a soybean field about 3/4 mile short of the runway. He then increased engine power to full, and the airplane climbed "a couple hundred feet." Once he established visual contact with the runway lights, he landed the airplane on the runway without further incident. The pilot added that the lateral guidance from the localizer was "dead center" but that he could not recall the position of the vertical guidance needle. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport’s automated weather observation station reported that, about 5 minutes after the accident, the wind was from 030° at 3 knots, visibility was 1/2 statute mile with mist, overcast at 200 ft above ground level (agl), temperature 57°F, and dew point 57°F. The pilot reported that the airport ceiling was overcast at 300 ft agl with fog and rain and that visibility was 1 mile.
Factual narrative
The pilot reported that while conducting the RNAV GPS RNY 08 instrument approach, at night in instrument meteorological conditions, about 50 feet above the decision altitude of 921 feet, he mistook building lights for runway lights. He inadvertently touched down in a soybean field, about ¾ mile short of the runway. He then increased engine power to full, climbed "a couple hundred feet", established visual contact with the runway lights, and landed without further incident. The pilot added that the lateral guidance from the localizer was "dead center" but he could not recall the position of the vertical guidance needle. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about 5 minutes after the accident, the wind was from 030° at 3 knots, visibility at 1/2 statute miles with mist, overcast at 200 ft above ground level (AGL), temperature 57°F, dew point 57°F. The pilot reported that the airport ceiling was overcast at 300 ft AGL, with fog and rain, and visibility was one mile.
