StockMarketWire.com - Engineering company Rolls-Royce said it faced deeper disruptions caused by a fault in its Trent 1000 engines.

The company, however, said its guidance for cash costs for the Trent 1000 Package B and C in-service issues in 2019 and 2020 was unchanged.

Rolls-Royce had already warned in August that the rate of recovery in Trent 1000 'aircraft on ground' had remained pressured, due to an additional repair load resulting from the faster deterioration of a turbine blade.

'Since then, we have also taken a proactive decision to accelerate intermediate pressure turbine blade replacement for the limited number of Package B and C engines yet to be fitted with the final standard of IPT blade,' it said.

'This has led to additional engine removals.'

'As a result, though we continue to work on further increasing our MRO capacity, these challenges mean that we now expect the return to single-digit level of aircraft on grounds on the Trent 1000 to be delayed until the second quarter of 2020.'

'We deeply regret the additional disruption that this will cause our customers and we continue to work closely with them to minimise the impact on their operations.' Story provided by StockMarketWire.com
