Within the 728 Jet Full Scale Fatigue Test, the Spoilers will be tested simultaneously to the wing loading. The spoilers are made of a CFRP sandwich with a solid Honeycomb core. The load assumptions are based on a rectangular pressure distribution on the spoiler surfaces. The loading point of the total spoiler force is the geometry of the trapezoid formed spoilers. The spoiler loads will be introduced in the structure by a pair of bellows on the spoiler surface. For certification of primary structure a fatigue test simulating 200,000 flights is recommended. The test scenario is divided into two phases - fatigue and damage tolerance. During the fatigue phase fatigue failures are not allowed to occur. For proof of composite elements and structure, the loads of the duty cycles have to be enhanced to 112%. The damage tolerance phase consists of 100,000 flights. During those flights all assumed failure modes are tested one after another. For each failure mode a test scenario of three times 5,000 flights is demanded at least. Every failure simulation will be ended by the application of limit load. The damaged structure has to withstand this load once for each failure mode.
