Ryanair has announced a new winter maintenance agreement with STS Aviation Group.

The UK MRO provider will perform two lines of heavy maintenance at its facility in Birmingham.

Ryanair previously announced that it had secured a winter maintenance agreement with Caerdav, another UK-based MRO.

The airline uses a mix of internal facilities and external suppliers to conduct its heavy maintenance.

Ryanair’s director of operations Neal McMahon commented: “Our five-year growth plan will grow our fleet to over 600 aircraft and we are pleased to announce this agreement with STS Aviation to conduct maintenance at their modern MRO facility in Birmingham this winter.

“This agreement will allow Ryanair to utilise two heavy maintenance slots, with aircraft coming in nose-to-tail for the upcoming winter season. STS Aviation has an excellent reputation for a quality service offering in the industry and we are pleased to be announcing this new deal. This agreement will ensure that Ryanair has flexibility as to where it places its aircraft for the winter maintenance season.”

STS Aviation Services’ senior vice president business development Europe Ian Bartholomew said: “We are delighted that Ryanair has selected STS Aviation Services to perform nose-to-tail lines of heavy aircraft maintenance at our facility located in Birmingham, UK. This contract win is testament to the professionalism and dedication of our entire team, and we look forward to receiving the first aircraft later this year while expanding the relationship and supporting the long-term growth of such a prestigious customer.”
