The Air Est Goeland (English: Gull), sometimes called the Clavé Goéland, after the designer, is a French parasol-wing, T-tailed, single-seat motor glider that was designed by Robert Clavé and produced by Air Est Services of Marly, Moselle in kit form for amateur construction.
The kit was supplied with two fuselage halves and the tail parts only, leaving it up to the builder to secure the Spatz wings and engine to finish the aircraft.
The specified König SC 430 18 kW (24 hp) radial engine is mounted in pusher configuration behind the wing and above the tail boom, although other similar engines can be used.
The aircraft features tricycle landing gear and a cockpit bubble canopy.
[1] In 1998 the basic kit was US$4400 and included just the fuselage halves and tail.
