Accident Overview
The accident occurred during an approach when the captain, despite having ILS glideslope data available, did not fly the glideslope. The partial obscuration of the airport environment due to ground fog contributed to the captain's failure to recognize that the airplane was high on both his approach and landing. The subsequent collision with a blast fence resulted in the destruction of the airplane and occupant injuries.
Investigation Findings
Examination of the aircraft revealed that passenger seats had been improperly assembled using unapproved parts, and seat belts had been installed incorrectly. These findings highlight maintenance irregularities but are not linked causally to the accident in the investigation.
Runway Safety Issues
The Federal Aviation Administration had engaged in persistent communication with local communities regarding runway safety area improvements and the installation of approach lighting for runway 6. However, these efforts were unsuccessful in gaining support for the enhancements.
Summary of Contributing Factors
The accident sequence involved the captain's deviation from the ILS glideslope and the obscuring effect of ground fog, which prevented timely recognition of the high approach and landing profile. The collision with the blast fence was the direct cause of the aircraft damage and occupant injuries.
