The Irish Coast Guard’s Rescue 116 Sikorsky S-92 helicopter had “no mechanical anomalies” before it crashed off the north Mayo coast with the loss of all four air crew, according to the Air Accident Investigation Unit (AAIU).

The AAIU , which has been analysing the “black box” or flight data recorder as part of its investigation, said that an initial analysis of the data retrieved from the aircraft’s health and usage monitoring system and multi-purpose flight recorder had shown no mechanical faults.

The statement issued by AAIU chief inspector Jurgen Whyte and investigator-in-charge Paul Farrell on Saturday said that the AAIU was mindful that Sikorsky S-92A helicopters are in operation around the world.

“Following an event such as this, many operators and agencies are anxious to learn if any matters are identified during the ongoing investigation that may require immediate safety actions,” it said.

CHC Ireland, which is contracted to provide air-sea search and rescue for the Irish Coast Guard, uses Sikorsky S-92s at its three operational bases in Shannon, Sligo and Waterford. Operations have been suspended at its Dublin base since the R116 crash.
