 The investigation into the accident was carried out by Turkey's Directorate General of Civil Aviation (DGCA).The cockpit voice recorder revealed that while the crew was struggling to regain control of the aircraft, at least some of the four flight attendants were inside the cockpit panicking and screaming.The copilot was heard telling the captain ""aman ağabey, gittik, gidiyoruz, bas.."" (which roughly translates into ""Oh brother, we've gone, we're going, push..."").
