In 1954 Yves Gardan designed the SIPA‑300 single jet‑engine tandem two‑seater ab-initio jet trainer. The construction of the prototype was launched on the basis of a contract awarded by the SALS.
First flown on September 4, 1954, by Max Fischl, it was powered by a 0.712kN Turbomeca Palas.
After thirty hours of flight testing by the manufacturer, the Sipa-300R entered the CEV Brétigny sur Orge April 4, 1955. On July 28 of the same year, it had accumulated 75 hours of flight and 99 landings.
This prototype was destroyed during a test spin on Sept. 26, 1955. No serial production was considered.
Fuel was in two tanks, one of 70 lt in the central wing and the other, 150 lt, housed in the fuselage.
