Eirtech Aviation has announced a major contract win with Southwest Airlines in the US.

The Shannon-headquartered Irish aviation services company said it has developed a solution for resolving a technical modification that affects Boeing 737 planes.

The fix has been mandated by the Federal Aviation Authority (FAA). By 2016, all owners and operators of Boeing 737's must complete the mandated modification on their aircraft.

''This is a significant contract and has lead to discussions with other airlines in North and South America, Europe, Asia and Africa, all of which are looking for a resolution that guarantees the fastest turn-around times matched by the highest standards with full regulatory compliance, at a cost that is competitive,'' commented Niall Cunningham, chief executive of Eirtech Aviation.

''The expertise of our teams has facilitated the development of a kit that will allow the aircraft to be modified with the minimum of disruption to client operations,'' he explained.

Eirtech Aviation was founded in 2009 after a management buy-out of Lufthansa Technik Painting Shannon and employs over 250 people, worldwide. As well as its Irish operations, the company has operations in the Czech Republic and Dubai. Its clients include Qatar Airways, Etihad, Air Berlin, Lufthansa and SAS.
