Iran Aseman Airlines has suspended ATR 72 operations until further notice, following the accident involving one of its turboprops.

The Iranian Civil Aviation Organisation says the airline is "temporarily ceasing" flights with both the -200 and -500 variants of the aircraft.

Investigators have yet to disclose any preliminary conclusions regarding the 18 February crash, which occurred in mountainous terrain as the aircraft approached Yasouj.

Iran Aseman Airlines has four remaining ATRs. The Civil Aviation Organisation says the carrier will resume flights with the type once it has ensured that their operation is safe.

Flight Fleets Analyzer indicates that the aircraft involved in the accident (EP-ATS) had been put into storage by the carrier in early 2011, and returned to service towards the end of last year.
