Aircraft manufacturer Boeing says it has been granted a license from the U.S. Treasury Department to export spare parts for commercial airplanes to Iran.
A spokesman for the company said on April 4 that the license covered a "limited period of time" and allowed the company only "to provide them spare parts that are for safety purposes."
Also on April 4, General Electric (GE) said it received U.S. permission to overhaul 18 engines sold to Iran in the late 1970s.
GE spokesman Rick Kennedy said that work would be carried out at GE facilities or at German firm MTU Aero Engines.
Kennedy said GE officials would meet with officials from Iran flag carrier Iranair and MTU in Istanbul next week to discuss Iran's needs.
Boeing said it would now contact officials in Iran to determine which parts were needed.
The sales would be the first acknowledged dealing between U.S. aerospace companies and Iran since the 1979 Islamic Revolution.
The step is being seen as part of an interim deal between world powers and Iran over Tehran's nuclear program.
Under the agreement signed in Geneva in November, Tehran agreed to freeze some nuclear activities for six months in exchange for partial sanctions relief.
