The Godbille JG.1B is a French light, two seat amateur built aircraft, dating from 1989. Only one was constructed.

Design and development

The JG.1B is a small sports aircraft with two seats placed side-by side. It has a polyester fabric covered steel tube structure and is a cantilever, low wing monoplane. Its straight edged wings carry inboard flaps.[1]

Conventionally laid out, the JG.1B is powered by a 78 kW (105 hp) Potez 4E-20B1 air-cooled flat four engine which drives a two blade propeller. The two occupants sit over the wing leading edge under a PET canopy, which blends at the rear into a raised, rounded fuselage decking. As the decking drops away rearwards, a long dorsal fillet leads to a swept, straight edged fin with a narrow triangular rudder. The tailplane is wire braced to the fin. The JG.1B's tail wheel undercarriage is fixed.[1]

The JG.1B gained its Certificate of Airworthiness on 15 November 1989.[2] It remains on the French Civil Aircraft register in 2014.[3]
