The Cierva C.12 was an experimental autogyro built by Cierva Autogiro Company in England in 1929 in association with Avro. Like most other Cierva designs it was based on an existing aircraft fuselage – in this case an Avro Avian. The most significant thing about this aircraft is that after initial tests the Avian’s second cockpit was removed and the aircraft’s undercarriage was replaced by the same floats used to equip standard Avian seaplanes.
