The UK is lobbying to stay in a key aviation safety organisation that will enable airlines to keep flying after Brexit.
Sky News reports that the UK is arguing for it to remain in the European Aviation Safety Agency (EASA) after Brexit. If it is not allowed to do so, the government will have to come up with a similar legal structure within weeks. US safety regulators are reported to be urging ministers to resolve the situation quickly.
Sky says that the Department for Transport has assured the industry that Britain will remain with EASA, particularly as 40% of the technical expertise behind it comes from the CAA.
Moreover, EASA has many member countries, including Switzerland and Norway, which are outside the EU, although they have no voting rights.
