Regulations allowed a freight-only mission but reports now suggest there were two passengers on board. Although the operator was given as Doren Air Cargo, the flight was said to be operated on nbehalf of Agefreco – a company that appears to have ceased trading in 2007.
The aircraft had disappeared from radio communication shortly before landing. Last Friday the crash site was discovered some eight nautical miles from the airport in dense jungle. None of the four people on board survived.
The Aviation Herald reported that there was fog in the area at the time of the crash and that the eventual crash site is just south of Mount Kahuzi which peaks at almost 11,000 feet.
