Rolls-Royce confirms transfer of work from Derby to Germany Rolls-Royce has announced that it will be shifting work from Derby to Germany to limit disruption caused by Brexit . The company confirmed in a trading update today that it is to transfer design approval work for its large aero engines away from Derby. Engines designed and built by the firm, which has its civil aerospace division in Sinfin ,have to be signed off by the European Aviation Safety Agency (EASA). There is uncertainty as to how this aircraft safety and design approval process would work when the UK leaves the European Union. That wasnt on that fucking bus.
