Aircraft Accident/Incident Report
Yankton, Oregon 97051
Monday, October 5, 2009 10:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he was flying to an airport to obtain fuel. He recalled approaching the airport and noting low clouds in the area, but could not recall anything further regarding the circumstances near the end of the flight. Air traffic control information showed that the pilot requested an instrument flight rules (IFR) clearance and was cleared for the localizer approach. FAA radar data and the accident airplane’s onboard instrumentation data showed that although the airplane was on course, it had descended below the minimum descent altitudes and collided with terrain approximately 8 miles from the airport. There was no indication that the pilot had the appropriate instrument approach chart available while conducting the approach. Examination of the wreckage revealed no evidence of a pre-impact anomaly. Toxicology findings are consistent with the pilot using an over-the-counter antihistamine on the day of the accident that has been reported to cause sedation. It is conceivable that the pilot may have been impaired by use of the antihistamine or distracted by the symptoms for which he had been prescribed the medication, however, it could not be conclusively determined whether the pilot's medication contributed to the accident.
NTSB Probable Cause Narrative
The pilot's inadequate planning during an instrument approach and failure to maintain the published minimum altitudes, which resulted in controlled flight into terrain.
