Chief Pilot was Erkan Sayin but I have to see if its still him. I'll also ask about the person in charge of hiring from some pilots at Onur Air. Will let you know.
This is information off another site regarding the airline hiring process, stated current as of March 2011:
Captain Peskadejzhe, DMD Operations
Captain Mert, Chief Pilot
Captain Arzhen, Fleet Director
A320/321
Captain Cyrus Yousefi, IOSA Agent
