I have known Aero Atelier for many years and have entrusted them with two engines over more than fifteen years of flying. They completely rebuilt the engine in my Cessna 150, delivering impeccable work with no subsequent problems. More recently, they overhauled the Lycoming O-320 in my BushCaddy L160. After about 300 flight hours, it is performing perfectly. I fly in the Far North, often in uncontrolled territory, in the mountains and on skis or bushwheels. In those conditions, reliability is essential. I have always had complete confidence in Aero Atelier.
