Iran Civil Aviation Organization (CAO.IRI) spokesman Reza Jafarzadeh said on 8 January 2020 that a team of investigators had been sent to the crash site.[1] The head of the commission for accidents in the Iran Civil Aviation Organization said that they received no emergency message from the aircraft before the crash.[32] It was reported that the aircraft's black boxes (the cockpit voice recorder and flight data recorder) had been recovered, but the CAO.IRI had refused to hand the devices over to Boeing.[33] Spokesman Ali Abedzadeh said it was not clear to which country the box would be sent so that its data could be analyzed.[29] Under standard International Civil Aviation Organisation rules, America's National Transportation Safety Board would participate in the investigation, as they represented the state of the manufacturer of the aircraft. France's Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile would participate as representatives of the state of manufacture of the aircraft's engines and Ukraine's Ministry of Infrastructure would participate as representatives of the state the aircraft was registered in. Given the current tensions in Iran, it is not known how these organizations would be involved, although it was reported that Iran had stated that American, French and Ukrainian authorities would be involved.[5]
