Over the past 20 years, Powerplant / Airframe Integration has become an essential step in the design of any transport aircraft. For the aircraft manufacturer, it is essential to reply to the program requirements in term of performance of the aircraft, to minimize the risks linked with the aircraft behavior in flight, and to reduce the costs and the development cycle. To achieve these goals, it is important for the Airbus partner in charge of powerplant / airframe integration to master the design of all related parts as pylon and nacelle aerodynamic lines. This paper describes the experience acquired by AEROSPATIALE MATRA AIRBUS on their products, highlighting the recent progress at each step of the design process. It is developed around the A340-
