What happened
A sightseeing flight, operating under Part 135 regulations for on-demand services, crashed into terrain after the aircraft transitioned from visual flight rules (VFR) into instrument meteorological conditions. During the flight, the weather conditions significantly worsened, with a passenger noting a decline in both visibility and the cloud ceiling. Local observers in the vicinity reported encountering dense fog, estimating the ceiling at approximately 50 feet and visibility at only one-fourth of a mile.
The accident resulted in six fatalities and one survivor. The occupants of the aircraft included individuals of various nationalities, including three Dutch and two Swiss citizens.
Findings
Investigations into the accident highlighted deficiencies in the operator's safety protocols. Specifically, the company's established training programs and operational procedures lacked guidance regarding VFR flight operations during marginal weather conditions. The lack of specific policy for navigating deteriorating visibility contributed to the flight's entry into instrument conditions while still operating under visual flight rules.
