Aircraft Accident/Incident Report
Rapid City, South Dakota 57703
Friday, December 29, 2006 2:00 MST
NTSB Narrative Summary Released at Completion of Accident
The airplane was on an instrument flight rules flight in night instrument meteorological conditions when the accident occurred. The airplane had been cleared for an ILS approach and the pilot elected to use a non-published procedure to intercept the final approach. After becoming established on the final approach, the airplane impacted the ground about 7 miles from the destination airport at an elevation approximately the same as the airport elevation. Flight inspections of the instrument approach performed prior to and subsequent to the accident revealed satisfactory performance of both the localizer and glideslope functions. The number one altimeter setting did not match the altimeter setting that was current at the time of the accident. Post accident examination of the altimeters revealed that the number one altimeter read 360 feet high. No determination was made as to whether the discrepency existed prior to impact. However, the pilot did not report any pre-flight discrepencies with regard to the airplane's altimeters. No other anomalies were found or reported with regard to the airplane's structure or systems.
NTSB Probable Cause Narrative
The pilot's failure to follow the published instrument approach procedure which contributed to his failure to maintain altitude and clearance from terrain during the instrument approach. A factor was the night light condition.
