I can confirm that my Department engaged Helios in 2015 to conduct an examination of the functions of Irish Aviation Authority (IAA) in accordance with Section 32 of the Irish Aviation Authority Act 1993.
My Department, with the approval of Government, has published the Executive Summary of the Report on the Department website. However, a decision was taken by the Government on the 18th of February 2016 not to publish the full Report.
The publication of the Report is currently the subject of a freedom of information request which is being reviewed by the Office of the Information Commissioner. Therefore, it would not be appropriate for me to comment further on this matter before the determination of the Information Commissioner has been made.
