The Air Accident Investigation Unit (AAIU) is part of the Department of Transport and is responsible for the investigation of aircraft accidents, serious incidents, and incidents (Occurrences) that occur within Ireland. In addition, the AAIU provides assistance to foreign safety investigation authorities who conduct investigations into occurrences involving Irish registered and/or operated aircraft abroad. Furthermore, in some cases, Foreign States may delegate Investigations back to the AAIU. The Chief Inspector of Air Accidents reports directly to the Minister for Transport. The AAIU headquarters is located in the Department of Transport, 2nd Floor, Leeson Lane, off Leeson Street, Dublin 2, D02 TR60.
