Survivor tells AP that 1 engine went out before Iranian airplane crash that killed 39

A survivor in the Iranian airplane crash that killed 39 people has told The Associated Press that one of the engines in the turboprop went out before it crashed.

Mohammad Abedzadeh said Monday that he saw the propeller not turning on as it ascended after takeoff Sunday from Tehran's Mehrabad airport.

The IrAn-140 operated by domestic carrier Sepahan Air crashed in a residential area near the airport, killing 39 people and injuring nine onboard.

Investigators continued to search Monday for the crash's cause.

Ali Reza Jahangirian, the country's Civil Aviation chief, told state television that one engine did go out, but the plane should have been able to fly. However, he said the reason for the crash will be determined once officials analyze data from the airplane's black boxes.
