THE COLLEAGUE of an aircraft engineer from Swords who fell seven metres to his death at Dublin Airport four years ago is seeking a new inquiry into the incident.Kevin Carroll from Wicklow is seeking a High Court order to direct new enquiries into the death of his colleague, David Ralph from Swords, who fell to his death when the basket of a de- icing rig broke free and crashed onto the apron at the airport. Mr. Carroll wants the Air Accident Investigation Unit and the Irish Aviation Authority to reopen the files on the incident and carry out new inquiries. He claimed in court that the Air Accident Investigation Unit and the Aviation Authority were obliged by law to fulfil statutory duties by inquiring into the endangerment of aircraft operations on the basis there had been a 'serious incident'. Mr. Carroll said he wished to issue proceedings involving the Investigation Unit, the Irish Aviation Authority and the Garda Siochana as well as the Minister for Transport, the Minister for Enterprise and Trade, the Health and Safety Authority and the Dublin City Coroner, Dr. Brian Farrell. Mr. Carroll was granted leave to bring a new application on September 18 on the basis the other parties would be put on notice and given an opportunity to put their side of the story to the court. Mr. Ralph's tragic death was witnessed by his partner, Catherine Kelly who was sitting in the de- icing truck when the basket the Swords man was standing in broke free and crashed to the ground. A rear pin holding up the basket had apparently shattered, causing the accident at 4.30 a. m. on March 19, 2008. The 58- year- old, from Brackenstown in Swords, Co. Dublin, suffered fatal head injuries in the fall. The couple were both employees of SR Technics at the time and had already deiced eleven planes when the incident happened. Mr Ralph had just started working on the rear section of a City Jet plane when the basket broke. He landed face down on the tarmac.
