Factual narrative

DURING THE TRANSITION FROM A DME ARC TO THE ILS FINAL APCH COURSE, THE PLT ALLOWED THE ACFT TO PREMATURELY DESCEND INTO THE GROUND. THE REASON FOR THE DESCENT COULD NOT BE DETERMINED. HOWEVER, NO PRE-IMPACT MECHANICAL MALFUNCTION WITH THE ACFT WAS FOUND NOR WAS THERE ANY EVIDENCE SUPPORTING PLT INCAPACITATION. DARK NIGHT CONDITIONS IN FOG AND LOW CEILINGS PREVAILED DURING THE APCH. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
