Rolls-Royce Holdings PLC (LON:RR.) has agreed with European regulators to an earlier-than-planned inspection of its Trent 1000 TEN engines after premature blade deterioration was identified.
The engine maker said it has been working closely with authorities to establish a plan for inspecting the remaining Trent 1000 Ten fleet to confirm the condition of the engines.

Rolls-Royce said it a small number of engines that have experienced a higher frequency of flights have needed to have their high-pressure-turbine blades replaced earlier than planned.
Last week, Singapore Airlines Ltd grounded two Boeing Co 787-10 jets fitted with the engines after checks found earlier than anticipated blade deterioration.
Rolls-Royce said its Trent 1000 TEN engines have been in service since November 2017 and there are currently more than 180 in service.
The group added that its cash-cost guidance on the Trent 1000 in 2019 and 2020 remains unchanged.
In February, the company said about 35 Dreamliners remained grounded and increased the exceptional charge related to problems with its Trent 1000 engines by £236mln for the full year to £790mln.
Additional charges, including £186mln on its Trent 900 programme following the decision by Airbus to stop production of the A360 superjumbo, dragged Rolls-Royce to a full-year operating loss of £1.16bn.
