The U.S. aviation company Boeing has announced a new agreement to provide airplane parts for Islamic Republic airlines, the first such agreement in 35 years.

AFP reported on Wednesday July 23 that Boeing documents indicate the U.S. company will provide parts and service to Iran in connection with flight safety.

This is the first time that Boeing has entered into an agreement with Iran since the 1979 Revolution and the beginning of U.S. sanctions against Iran.

Earlier this year, Boeing and GE, two American companies, announced that they had received permission to provide parts for Iran’s passenger planes.

Iran’s aviation officials have said that Iran has 100 airplanes that are out of service due to a lack of parts.
