Air accident investigators are expected to release a final report shortly into the 2011 plane crash in Cork Airport that killed six people.
Several recommendations from the report are expected to have an impact across Europe's aviation industry.
Six people were killed when the Manx2 aircraft en route from Belfast to Cork crashed on its third attempt to land in dense fog at Cork Airport on February 10, 2011.
The investigation by the Irish Air Accident Investigation Unit has been one of the most detailed, complex and comprehensive ever undertaken by the body.
Some of the more significant recommendations are expected to have implications across Europe’s aviation industry.
The IAAU's interim statement revealed a sensor fault which affected fuel flow to and power output from the engine of the aircraft.
However, investigators have spent the last two years focusing on wider systematic issues relating to the ill-fated commuter flight for the upcoming report.
The report has been issued to all the relevant parties including the survivors, the families of those who died and their legal representatives.
