The Transat was designed to comply with both French microlight and US light-sport aircraft rules. It features a biplane layout with two seats in side-by-side configuration within an enclosed cockpit, fixed conventional landing gear and a single engine in pusher configuration.[2]
The aircraft fuselage is made from composites, with its flying surfaces covered in doped aircraft fabric. Its 8.81NaN1 span wing has an area of 18m2. The standard powerplant is a 800NaN0 BMW 1100RS fuel injected, four-stroke engine. The landing gear is retracted electrically, with a back-up manual system. The Transat is advertised as the only amphibious microlight that can take-off from water at maximum gross weight in under 15 seconds.[2]
