Aerial Operation

On Wednesday morning (Feb. 21), Iran�s Army Spokesman General Shahin Taqikhani said� that adverse weather conditions has made it imposslibe for the helicopters to continue aerial operation for transferring bodies of victims of the doomed ATR plane.

After an intense search operation for the missing flight, choppers of the Islamic Revolution Guards Corps (IRGC) found charred wreckage of the plane bearing the Aseman Airlines insignia on Tuesday (Feb. 20).

Citing the heavy fog that has reduced visibility to only 2 meters in the zone and has prevented any helicopter flights, General Taqikhani said the rescue teams were figuring out how to transfer the bodies on the ground.

In a meantime, four IRCS helicopters had flown over the region as part of efforts to find the crash site. Iran�s Air Force F-14 fighter jets also flew over Dena Mount while army parachutists and commandos along with mount climbers continued the ground search and rescue operations.

ATR Investigation Teams

Civil Aviation Organization (CAO) announced that seven French personnel arrived in Tehran on Tuesday night (Feb. 20), to cooperate in the investigation into an ATR plane crash in central Iran.

Three members of French government�s Committee on Investigating Incidents and four members from the factory producing the plane arrived in Tehran.

Renovating Aging Fleet

On April 10, 2017, Iran�s national flag-carrier airline Iran Air has signed a contract to buy 20 turboprops from ATR.

The contract between IranAir and ATR to buy 20 ATR 72-600 aircrafts was signed by the officials of both countries.

The 70-seat ATR planes are aimed at domestic routes, which Iran seeks to revitalize after the lifting of sanctions in early 2016.

Iran is also renovating its aging fleet for international or long-distance flights under deals signed with Airbus and Boeing to buy a total of 180 passenger jets.

This is while officials at the Trump administration are using a case against an Iranian airliner to thwart a multibillion-dollar deal between Boeing and Iran Air for the sale of new passenger planes, US reports say.

Trump has taken an aggressive stance on Iran, and pledged to ditch a landmark nuclear agreement which made the Boeing deal possible if radical changes are not made in the accord.

Under the deal, limits were put on Iran�s nuclear activities in exchange for, among other things, the removal of all nuclear-related bans against the Islamic Republic.

Since taking office, US President Donald Trump repeatedly threatened to kill Iran nuclear agreement signed between Iran and world powers on July 14, 2015.
