Rolls-Royce says it has "made progress" in its investigation into the cause of engine problems on the Airbus A380.
The firm did not say whether its engineers had identified what caused one of its engines to break apart on a Qantas flight last Thursday.
But it said the problem was specific to the type of engine being used on the plane.
Qantas, the Australian airline, has grounded its entire fleet of A380s for further checks.
The BBC's Hugh Pym reports.
