We purchased a Lycoming IO 540 engine from Aero Atelier for our company test aircraft, a Van’s RV-10, used for avionics development. From the beginning, the experience was excellent. The team built a very high-quality engine and ensured everything was properly prepared. Communication was clear, professional, and very supportive throughout. The engine has performed reliably and exactly as expected. It is great to know that we have such a strong and reliable engine supplier here in Canada.
