Like Niloufar said , it is Antonov aircraft with a capacity of over 50 persons.These airplanes are now being manufactured by the Aircraft Manufacturing Company of Iran (HASA) under the name of Iran-140
thanx guys for the info about the plane. I thought it was the Iran H-140, it's good to see TM has faith in vatany design. As much as I endorse vatany "things", my heart jumped when I saw them getting into that plane.
