Category:Accident
Location:Bloomington, IN -   United States of America
Phase: Approach
Nature:Private
Departure airport:Lafayette, IN (LAF)
Destination airport:Bloomington, IN (BMG)
Investigating agency: NTSB
Narrative:
The airplane crashed into trees about 1/2-mile from the approach end of runway 35 while the aircraft was conducting a precision instrument approach in night instrument weather. The flight's plotted radar data was consistent with an airplane that was being vectored for an instrument landing system (ILS) approach. The radar track depicted the aircraft flying above glide path and to the right of course until radar contact was lost at 2,000 feet at 2338:34 about two and a half miles from the approach end of the runway. About 2345, the Sheriff responded to telephone calls of a possible airplane crash. A witness described the airplane sounds as an engine acceleration, followed by a thud, and then no more engine sounds were heard. The airport's weather about the time of the accident was: Wind 230 degrees at 5 knots; visibility 1 statute mile; present weather mist; sky condition overcast 100 feet. The published decision height for the approach was 200 feet agl and one-half mile visibility. A post accident inspection of the ILS determined the ILS was operating normally. The tower did not record after hour radio transmissions. An on-scene examination of the aircraft wreckage did not reveal any pre-impact anomalies. A review of data from an engine monitor showed a reduction in fuel flow consistent with a descent followed by an increase in fuel flow consistent with a full power setting.



Probable Cause: The pilot's continued descent below decision height and not maintaining adequate altitude/clearance from the trees while on approach. Factors were the the night lighting conditions, and the mist.
