Accident Overview
An aircraft operating under Instrument Flight Rules (IFR) was cleared for an Instrument Landing System (ILS) approach to the airport. At the time of the accident, low ceilings and fog were reported at the airport. Radar data collected during the approach showed that the aircraft's heading varied numerous times from one side of the approach to the other.
Accident Location
The aircraft was found in a wooded area approximately one mile from the airport, directly on the centerline of the ILS. The location suggests the aircraft remained aligned with the approach path despite the heading deviations.
Equipment Examination
Post-accident examination of the aircraft revealed that the navigational instruments on board were operating within factory specifications. Additionally, the airport's ILS was examined and found to be operating within specifications.
Conclusion
The investigation did not identify any mechanical or system anomalies as a cause for the deviation and subsequent accident. The aircraft's navigation instruments and the airport's ILS were both functioning correctly. The reason for the heading variations observed on radar remains undetermined based on the available information.
