Accident Overview
Shortly after reporting the outer marker while executing an ILS Runway 18 approach in actual instrument meteorological conditions, the aircraft deviated left of the localizer centerline. At a position approximately half a mile outside the middle marker and about a quarter mile left of the localizer centerline, the aircraft descended into a wooded area on an easterly heading. The aircraft impacted the trees and then the terrain in a slightly left bank and slightly nose-low attitude.
Investigation Findings
Engine examination and teardown revealed no evidence of pre-impact malfunction. A flight check of the ILS Runway 18 was performed the following day and indicated the system was functioning normally. Inspection of the aircraft instruments did not disclose any malfunctions. The pilot was in contact with air traffic control and did not report any problems before the impact occurred.
Pilot Information
All pilot records were destroyed by post-impact fire. The pilot's total instrument flying experience was not determined; the instrument rating was obtained on January 3, 1987.
