It is a single-engined monoplane with a fixed tricycle undercarriage, conventional control stick, and is, unusually, fitted with a V-tail.

Robin won the competition in 1983 with their ATL design, a single-engined low-winged monoplane with a fixed undercarriage and a V-tail.

[1] The first prototype flew on 17 June 1983, powered by a single 35 kW (47 hp) JPX PAL 1300, a new design of two stroke, three-cylinder radial engine.

[2] First orders, for 30 ATLs were placed by the French National Aviation Federation in November 1983, with initial deliveries starting (under a limited airworthiness approval) in April 1985.

[4] One solution to this problem was re-engining with a more reliable engine, and Robin developed a version for the German market powered by a 52.5 kW (70 hp) Limbach.
