Irish Aviation Authority (IAA)
"Irish leasing companies appear to be in a strong position to get involved in any contracts being negotiated. Ireland is one of the world's leading locations for aircraft leasing companies and, on February 11, the Civil Aviation Organization of Iran (CAOI) signed a cooperation agreement with the Irish Aviation Authority (IAA), covering aircraft leasing, flight supervision and maintenance and repair among other areas... Iran Aseman Airlines is set to be one of the first to take advantage of that agreement. It is planning to lease seven Airbus A320neo aircraft and "the terms of this contract [with the IAA] will apply as soon as these aircrafts land in Iran after being registered in Ireland," according to the CAOI."

"Iran and Ireland signed a memorandum of understanding (MoU) early on Wednesday morning, Iran’s Civil Aviation Organization (CAO.IRI) announced. The agreement, signed by CAO.IRI’s Mohammad Javad Taghvaei and the Irish Aviation Authority’s Ralph James is reportedly the first ever aviation agreement between the two countries." (February 8, 2017)
