What happened
During a night operation under instrument meteorological conditions, the pilot was executing an instrument landing system (ILS) approach. The aircraft was observed descending toward the runway threshold, reaching an altitude that aligned with the established approach decision height. At the time of the incident, local weather conditions were characterized by thick fog and extremely low visibility, with a reported ceiling of 100 feet and visibility of only 0.5 statute miles.
A witness near the airfield noted the aircraft passing overhead and initially believed a missed approach had been initiated, as the engine noise appeared to be at cruise power and no unusual sounds were heard. Shortly after this observation, airport operations reported that a crash had occurred. The aircraft struck the ground approximately 3,500 feet past the approach end of the runway, landing roughly 0.25 miles to the left of the runway centerline.
Findings
An inspection of the aircraft following the impact showed no evidence of mechanical malfunctions occurring prior to the crash. The environmental conditions at the time of the accident were described as pitch black with heavy fog.
