Minister for Transport Shane Ross is appointing an international team of aviation experts to review “oversight” of the State’s air-sea search and rescue provision.

Mr Ross, who holds responsibility for the Irish Coast Guard, is acting on an Air Accident Investigation Unit (AAIU) interim recommendation made to him after the fatal Rescue 116 helicopter crash.

The team led by a former European Aviation Safety Agency rulemaking director Professor Jules Kneepkens is being given two months to report back.

Four Irish Coast Guard air crew – Capt Dara Fitzpatrick, Capt Mark Duffy, winch crew Paul Ormsby and Ciarán Smith – died when their Sikorsky S-92 helicopter crashed on Blackrock island, 13km west of the Mullet peninsula in the early hours of March 14th, 2017.

The bodies of Capt Fitzpatrick and Capt Duffy were recovered, but the two winch crew remain missing.

The AAIU is still investigating causes, but its interim statement published just over two months ago called on Mr Ross to conduct a “thorough” review of search and rescue aviation operations in the State. It said this was required to ensure “effective continuous, comprehensive and independent oversight”.

The Irish Times are today reporting that the interim statement also recommended that CHC Ireland – the air crew’s employer – should review its safety management systems, which the investigators expressed concern about.

A third interim recommendation, for helicopter manufacturer Sikorsky, related to a software issue in data recording, which is not directly relevant to the cause of this crash.

Working with Prof Kneepkens will be Rowan Greenwood, a former Bristow Helicopters search and rescue commander on contract to the British Coastguard, and International Civil Aviation Organisation safety oversight auditor Milen Dentchev.

A number of other coastguards have also offered to assist in the review, according to Mr Ross.

The Minister said that Prof Kneepkens, who is also a former director-general of civil aviation in Belgium and the Netherlands, brings “vast experience in the international regulatory field”.

The blend of search and rescue operational and international civil aviation audit expertise in his team “should ensure the review meets the requirements of the AAIU’s recommendation”, Mr Ross said.

Mr Ross said the independent team would enable him to report “good progress” to the AAIU by mid-June, which is the “next reporting milestone” for the various safety recommendations in the continuing investigation into the crash.

The AAIU final report is expected to take some months, while a separate joint investigation is also being conducted by the Garda and Health and Safety Authority.
