This report describes the findings of subtask A1 of the project EuropeanWind Turbine Certification (EWTC). The main objective of the EWTC project is to realize a uniform harmonised wind turbine certification in the European Union, in order to remove trade barriers, speed up implementation and further reduce wind energy costs. The harmonised certification should be adjusted to the needs of the wind energy industry and the requirements of the European legislation. The objective of the subtask A is to collect viewpoints of the manufacturing industry on wind turbine certification. A questionnaire has been distributed to the European wind turbine manufacturing industry, asking for experiences with the present certification systems and for specific wishes for improvement within harmonised certification. Responses have been received from 13 companies. Their answers to the various questions are presented in this report. Wind turbine type certification is experienced as quite useful, but in view of the time involved and the high costs, wind turbine manufacturers put forward various suggestions for an improved certification system which is harmonised on the world-wide level
