[3] At its root, the wing merged gently into the fuselage with small air intakes for the 1.47 kN (330 lbf) Turbomeca Palas engine built into the leading edge.

The cockpit was placed just aft of the intakes and the long straight-edged fin, swept at about 75° and initially as wide as the cockpit, began immediately behind it, narrowing to a slightly swept trailing edge carrying a full depth rudder.

[1] Ten hours of manufacturer's testing was followed, in April 1954, by assessment at the Centre d'Essais en Vol (CEV), Brétigny-sur-Orge.

[1] At the time of its appearance at the 12th Salon International d'Aeronautique at Paris, in 1957, the undercarriage legs were faired and the main wheels enclosed in spats[6] and the aircraft renamed the Pa 49B.
