The project group will through this report investigate the uncertainties regarding fatigue design of a wind turbine jolt. The test series forming the background of \citep{EC-1993-1-9} are analysed, and the significance of the scatter included is evaluated. A nonlinear SN-curve is implemented due to the uncertainties regarding the location of the knee point of bilinear SN-curves. Estimates of a Low Cycle Fatigue load is proposed, and the resulting accumulated reliability is analysed by a probabilistic approach. This is done in order to quantify the possible trimming of design parameters, when designing for Fatigue loads
