Ryanair is to open its first maintenance and repair facility in Ireland at a 5,000sq.m hangar in Shannon, as part of a €10m investment.
It is expected the facility will employ 200 staff to maintain its fleet of more than 500 aircraft.
The new maintenance hangar will be leased from the Shannon Group by Ryanair.
The maintenance work will be carried out by Prestwick Aircraft Maintenance, a Scottish company that has Ryanair as its only client.
Up to now, maintenance and repair work on its fleet has been carried out in Scotland and also in Lithuania.
Ryanair said the new facility will support the maintenance and repair of its aircraft as it expands its fleet from 500 to 600 between now and 2026.
The airline currently flies to more than 230 destinations across Europe and North Africa.
It operates more than 115 services out of Dublin, 25 from Cork, 23 from Shannon 15 from Knock and seven from Kerry Airport.
The company is investing €10m in leasing the three-bay facility at Hangar 5 in Shannon, one of ten hangars now fully occupied on the Shannon campus and employing over 3,000 in this work across a number of companies.
Ryanair Director of Operations Neal McMahon said the Shannon facility is the airline's first heavy maintenance facility in Ireland.
He said it demonstrates the company's commitment to the midwest and to Ireland as it drives post-pandemic recovery through connectivity, inbound tourism and employment.
Shannon Group CEO Mary Considine said it is a significant investment in the future of the airport, creating high-quality jobs for local aviation specialists, increasing economic activity, and retaining skills and talent in the region.
