Oisín joined the Air Corps in 2002. After nine months military training at the Officer training facility in the Curragh, Oisín returned to Baldonnel to begin his flying training. He formed part of the three strong 23rd Regular Air Corps Cadet Class and received his military pilot’s wings and presidential commission as an Officer in the Air Corps in September 2004. Oisín began his flying career in a Cessna 172, flying a range of missions across the country while building valuable flying experience. After 6 months, he returned to the Flying Training School where he flew the PC-9M and held a ground appointment as an administration Officer in Air Corps college. From there, Oisín moved to No. 3 Operations Wing and completed his helicopter conversion course. He was dual rated and flew numerous missions in both Eurocopter EC135 and Agusta Westland AW139 helicopters. These missions included a wide range of tasks including VIP transport, air ambulance, troop transport, winching, fast roping, abseiling, helix casting, mountain flying and air gunnery. Oisín also served in the Garda Air Support Unit, flying the Garda Helicopter across a wide range of taskings. In February 2013, Oisín was selected for a flying instructor’s course. He completed the course on the PC-9M and once complete returned to the Garda Air Support Unit as the Chief Helicopter Instructor. His roles now include helicopter pilot training in both ab initio and operational roles. He is the holder of a Commercial Pilots License (CPL) for both fixed wing and helicopters with ATPL knowledge, helicopter single pilot multi engine instrument rating and is also one of the few qualified night vision goggle flying instructors in the country.
As a keen sportsman his entire life, Oisín has represented Ireland in surf-lifesaving and triathlon. He has numerous international medals, made up of both European and World Championship titles and was awarded European Lifesaver of the year in 2012.
Oisín holds a first class honours degree in Aeronautical Engineering from the university of Limerick and this inspired his love of drone flying. Along with Gearóid he created the drone training course for pilots in Ireland and is also an drone pilot examiner on behalf of the Irish Aviation Authority.
