Rolls-Royce's Dreamliner sounds safety alert over turbine cracks

AIRCRAFT engine maker Rolls-Royce has been hit with complaints of design faults in its Trent 1000 turbine that powers the already troubled Boeing 787 Dreamliner, reports Bloomberg.

This adds to the of design faults that have plagued the engine since 2016. The glitch concerns the cracking of discs in the model's low-pressure turbine as they rub against nearby seals.



The European Union Aviation Safety Agency said it plans to issue an airworthiness directive on the matter, which could lead to damage and reduced control over the aircraft if not fixed.



Faults with the Trent 1000 have resulted in more than a billion dollars in charges and helped General Electric win a larger share of engine orders on the 787.



Rolls-Royce said it aims to reduce Trent 1000 groundings for remedial work to no more than 10 at a time as flights resume after coronavirus lockdowns. The London-based company said the new problem shouldn't affect that goal.



'We do not anticipate it will cause any significant operator engine maintenance burden,' a spokeswoman said. 'We are developing a design solution which will remove the need to inspect these parts.'
