The first storms of autumn claimed their first blade in the Netherlands on September 12. During gusty winds a blade was broken from a privately owned Tacke turbine on Holland's Noordoostpolder at Espel. The other six 600 kW Tacke units currently installed in the Netherlands were immediately shutdown pending the results of investigations. According to Arthur Vermeulen of Tacke's Dutch agent, Hollink, "The cause of the failure should be known within a week or so, but a manufacturing fault could well be the cause." The blade failed about three metres from the hub and landed close to the base of the tower. The seven Dutch turbines had, until July of this year, been equipped with Abeking and Rasmussen blades which are standard issue on the company's 350 German machines. However, as these blades are not certified in Holland they were replaced by carbon reinforced blades from French manufacturer, Atout Vent. Vermeulen finds it ironic that the blade certified by national laboratory ECN should fail at the first sign of bad weather whereas "in general we have had no problems with our normal blades, either here or in Germany."
