The Hennion was a two-seat French training and touring aircraft, completed just before World War II began.
[1] The fuselage was flat sided and ply skinned, except behind the cockpit where rounded, raised decking was fabric covered.
The Hennion's cockpit was fully enclosed under a two piece canopy with a sliding rear component.
[1] At the rear the vertical tail was tall, with an unbalanced rudder which reached down to the keel and a fuselage mounted tailplane ahead of it.
[2][4] After a period of disuse, it was re-engined in 1956 with a 48 kW (65 hp) Continental A65 air-cooled flat-four in a revised nose and redesignated the Hennion II.
