Rolls-Royce warns that engine trouble will hit profit

Rolls-Royce has warned that problems with its Trent 900 engine – which forced on plane into an emergency landing – are likely to hit profit this year.

The company has been investigating an explosion of an engine that forced an emergency landing of a Qantas A380 jet last week.

Rolls Royce said the problem has been isolated to a specific component and only affects the Trent 900.

It said in its announcement that profit growth may be "slightly lower" as a result.

Qantas grounded its fleet of six A380s after an engine exploded on a flight to Australia on 4 November.

The plane made an emergency landing in Singapore.
