Principles of the EF2 (French acronym for trial fatigue 2) test of a center fuselage and wing are given. The goal of the test is to verify that the A330/A340 structure reaches or exceeds its design goals. The A330/A340 structures are almost identical, but differ with respect to the number of engines and will be subjected to different mission profiles. One combined test specimen was defined. The test will be divided into two phases beginning with combined loads of the A340 short and medium range versions up to 40,000 flights, followed by A330 short range loading up to the test end, resulting in a total of 80,000 flights. The test specimen is illustrated and its control and loading described. Methods to verify the damage tolerance behavior of the A330/A340 primary structure and to investigate the fatigue and damage tolerance behavior of aluminum lithium material which makes up part of the EF2 fuselage structure are summarized.
