Companies operating Boeing 787 planes as well as other jets powered by Rolls-Royce Trent 1000 are required to check the engine over a possible risk of cracking, the European Union Aviation Safety Agency (EASA) has said.

A new “potential unsafe condition” has been discovered in low-pressure turbine discs of the engine, which previously caused multiple Boeing 787 groundings. The EASA said that rubbing between the discs and interstage static seals could lead to cracks in the front seal fins. (RT)
