Spokesman Tim Neale said, “Under the US sanctions currently in place against Iran, we cannot have any dealings with Iran’s airlines even on safety of flight matters unless the US government gives us permission to do so. The last time the government licensed us to provide a part for an Iranian commercial jet was in 2000, when we were licensed to install an FAA-mandated strut modification kit on an Iranian 747 at a location outside Iran.” The FAA is the Federal Aviation Administration.
