Iranian Boeing 747 made an emergency landing at the airport in Tehran because one of its four engines started to fall to pieces in the air.
Abbas Asllani, local journalist, published some of the photos of engine unit components that have fallen in the outskirts of Iranian capital on his twitter account. They also display the engine condition after landing in Tehran.
According to Asllani, there were more than 300 people on board the aircraft. All people are safe. The aircraft was making a domestic flight from Tehran to Bandar Abbas. No information on the airline is specified.
Iran is suffering from sanctions of Western countries for years already, which prevents its airlines from renewing their air fleet with modern aircrafts as well as maintaining the technical condition of the operated aircrafts at a proper level.
In April 2014, the US Treasury allowed Boeing to export a range of spare parts for commercial aircrafts of Iran in order to ensure the flight safety. This was done in the framework of agreements on the relaxation of sanctions in return for a deceleration of Iranian nuclear program
