According to Avherald:
"On Sep 5th 2016 Senegal's BEA released a brief interim statement reporting that the investigation has been almost completed, the final report is currently being drafted and will then be sent out to the parties involved for comments that can be submitted within 60 days. The resulting final report will then be published. The BEA reported that the HS-125 has not been found, the search for the aircraft has been formally suspended, the aircraft thus remains missing. The BEA have analyzed records of flight operations, maintenance and monitoring of both the Ceiba Intercontinental as well as the Air Senegal aircraft as well as enforcement of aircraft and crew certification."
