Rolls-Royce claims to have made progress on understanding the cause of the engine failure that forced a Qantas superjumbo jet to make an emergency landing.
The manufacturing giant said it had become clear the incident was specific to its Trent 900 engine and stressed it was the first such failure of one of its large civil engines for 16 years.
Rolls added: “We are working in close co-operation with Airbus, our customers and the authorities, and as always safety remains our highest priority.”
Shares in the group pulled back into positive territory, up more than 2%, having earlier slumped by 4% after the chief executive of Qantas said oil leaks were discovered in three engines on its superjumbo fleet.
Qantas grounded six A380s after an engine burst minutes into a flight from Singapore to Sydney last week, scattering debris over Indonesia’s Batam island.
