donpizmeov, the problem with anonymous treads are people who trying to apply common practice and common sense to this particular problem without realising there is very little common sense in US sanctions but they exist anyway and no large company like CFM or DY can risk bypassing it like smaller companies do by asking garage of friend Mohammed to ship them a junky JT9 from Ras-el-Kaimah to Tehran. This is the Leap engine and this is a major airline, I truly hope they don't need to drop an engine. Getting just a part could be much easier and don't attract much attention. It will not work like that with a complete engine like Leap to be shipped from OEM, it is totally different story from JT8/JT9/old211/cfm-3 and other old garbage available from hundreds of sources. Another poster have correctly mentioned the typical timeframe to get a nod from OFAC even if it is a genuine case of no wrongdoing.
