Analysis narrative
During the second ils approach the airplane descended below the glidepath and impacted the terrain 2,500 feet short of the intended landing runway. The pilot indicated that a failure in the approach lighting system contributed to the accident. A post accident functional check of the approach lighting system failed to reveal any anomalies.
