Additional Trent engine inspections to disrupt quarter Boeing 787 flights

Additional Trent engine inspections to disrupt quarter Boeing 787 flights

"The increased inspection frequency is driven by our further understanding of the durability of the Trent 1000 Package C compressor", the British engine maker explained, adding that the move would "unfortunately lead to additional disruption for our customers" as well as higher cash costs than previously guided.

"The increased inspection frequency is driven by our further understanding of the durability of the Trent 1000 Package C compressor, a condition that we highlighted earlier this year", the company said, adding that there are 380 Package C engines now in-service with airlines.

Rolls-Royce has been plagued by issues with the blades in the Trent 1000 engine model, which is used in Boeing 787s, and some Trent 900 engines, amid reports of early corrosion or wear to parts.

Rolls-Royce Holdings plc, an engineering company, develops, manufactures, markets, and sells power and propulsion systems in the United Kingdom and internationally.

Boeing said the 787 has safely flown more than 3.2 billion miles since entering commercial service in 2011.

"We will be working closely with Boeing and affected airlines to minimise disruption wherever possible", Chief Executive Warren East said.


Airlines operating some of the engines have been ordered by global safety regulators to carry out more regular checks on them, meaning they will be grounded much more frequently for maintenance.

The checks will be made on a batch of 380 Trent 1000 turbines after testing indicated that more frequent scrutiny is required to cope with an existing durability issue, Rolls-Royce said in a statement Friday, barely a month after the London-based company suggested the problem was under control. "Our team of technical experts and service engineers is working around the clock to ensure we return them to full service as soon as possible". Virgin has also leased three Airbus A330-200s to help cover its flying programme.

It stresses that neither the Trent 1000 TEN powerplant nor the Package B version of the engine will be affected by the new inspections.

Scoot, a budget carrier owned by Singapore Airlines, said it expected some impact on operations.

Trent 1000 Package C engines that have operated fewer than 300 cycles are unaffected by this directive.

In March, Rolls said the cash hit from the problem should peak at £340mn in 2018 before falling in 2019.
