(1st July 2025, Shannon, Ireland) Denise Mangan-Fahy has been confirmed as the next Chief Executive Officer of Shannon Engine Support (SES), an organisation jointly owned by AerCap and Safran Aircraft Engines which specialises in providing spare engine leasing solutions to businesses around the globe.

Denise has worked in the aerospace industry for 35 years, initially with Shannon Aerospace before joining GE Capital Aviation Services (GECAS) in 1998 as VP Engine Management, rising to SVP Portfolio and Rental Operations in 2018. With AerCap’s acquisition of GECAS from GE in 2021, Denise became Head of Portfolio & Rental Operations for AerCap Engines.
She succeeds Julie at a time when the business has grown to become one of the true leaders in its space, delivering CFM engines (including the CFM56s and LEAP engines) to airline customers around the globe. The ambition for the business is to have 700 engines under management by the end of 2025, and up to 900 by the close of 2028.
Denise Mangan-Fahy shares her vision for the future: “I would like to thank Julie for her outstanding leadership and dedication in positioning SES as the number one lessor of CFM56 and LEAP engines worldwide. In my new role, I will continue to drive SES’s vision of operational excellence and portfolio growth whilst delivering on our customer requirements. I look forward to a seamless transition and to working with the SES team for many years to come.”
Denise and Julie were contemporaries from their time as GECAS, which Julie joined in 1997 Julie was appointed CEO of SES in 2013. “When I joined, there were around 28 of us, we had a portfolio of 200 engines,” Julie explains. “Today we have more than 100 employees and a portfolio of over 600 owned and managed engines. With Denise’s appointment I know that I am passing on the company to someone who values our people, for it is the long-term relationships that they build and nurture, and their technical skills which have always been the foundation of our success. She is also inheriting a senior leadership team that is second to none and a business that is admired by its peers.”
