Rolls-Royce remains on track to roll out upgraded Trent 1000 TEN high-pressure compressor turbine (HPT) blades around mid-2021 and does not expect to see any more unplanned Boeing 787 groundings linked to the issue or other identified problems with the engines.
“We have continued with the development work on the final fix for the HPT blade on the Trent 1000 TEN, and we remain on track to start installing that by the middle of next year,” CEO Warren East said during a Dec. 11 investor-update call.
The original HPT blades entered service with a limit of 1,000 cycles, with some needing to be swapped out even sooner. Rolls pledged to develop a more durable blade, but the work was delayed, with the company announcing in late 2019 that mid-2021 was the revised target for rolling it out.
