Accident Overview
On a final ILS approach to Charleston-Kanawha Airport, a twin-engine airplane descended 1,000 feet below the glidepath and collided with trees. The aircraft then crashed in flames in a wooded area a few hundred yards from the runway threshold. The pilot and two passengers were killed, and two other occupants sustained serious injuries.
Flight Conditions and Sequence
The approach was conducted in marginal weather conditions. According to the official investigation, the pilot continued the descent below the glidepath during an ILS approach under low ceiling and fog, with visibility reported as half a mile or less. The airplane crashed inside the outer marker while 1,000 feet below the glidepath.
Probable Cause and Contributing Factors
The probable cause of the accident was a collision with trees on final approach after the pilot attempted an operation beyond experience and ability level. Contributing factors identified by investigators included improper IFR operation, incorrect trim setting, high obstructions, low ceiling, fog, visibility half a mile or less, the ILS approach, and the fact that the pilot did not hold medical, multi-engine, or instrument ratings.
