One major design fix remaining for the Trent 1000

Rolls Royce has announced it has made progress in resolving its Trent 1000 issues, with only one major design fix remaining.

Warren East, CEO of Rolls-Royce said: “We have completed a detailed technical evaluation of our work on an improved high pressure turbine (HPT) blade for Trent 1000 TEN, the last major redesign activity required for the issues which we have identified with the engine.

“Although we regret that the blade will not be ready when we had originally planned, our understanding of the technical issues has significantly improved. As a result we are now able to reset our financial and operational expectations for the engine based on a blade design with a prudent durability estimate that we are confident we can deliver.”

Improving the high pressure turbine blade for the Trent 1000 TEN – the final fundamental issue to address – has been postponed to 2021.

Based upon recent testing and detailed technical evaluation the company is resetting financial and operational expectations for the Trent 1000 TEN based on a more conservative estimate of final HPT durability. This work will provide its customers with a clearer view of their fleet’s servicing requirements.

To minimise the impact on customers, further actions underway including accelerated investments in additional maintenance capacity and spare engines to reduce disruption.

Warren East, CEO of Rolls-Royce said: “In spite of improved trading since the half year, we now expect full year operating profit and free cash flow to be towards the lower end of our guidance ranges. in civil aerospace, while the trent 1000 costs remain a headwind, the vast majority of our installed fleet of widebody engines is performing well, with the Trent XWB surpassing our expectations.”
