Airbus is yet to commit to a maiden flight date for its A330neo, but both engines have been fitted to the initial test aircraft.
The aircraft, a -900 variant, is currently in a "preparatory test phase", says the airframer.
Airbus has not disclosed a window for the first flight but says it expects this to take place "in the coming weeks". It had admitted earlier this year that the A330neo might not fly until September, but it has not confirmed whether a flight this month is likely.
The original development schedule for the A330neo aimed for entry into service at the end of this year.
But delays in the programme, particularly with the Rolls-Royce Trent 7000 engines, have resulted in a shift of several months.
Airbus has secured orders for 210 A330neos, all but six of which are -900s.
