Airbus will cut production rates of the A330 to nine a month from 10 in the fourth quarter of 2015 as it switches to an upgraded version of the jet, the A330neo.
Airbus launched the A330neo at Britain's Farnborough airshow in July and it is due to enter service in the fourth quarter of 2017.
Analysts had expected a production cut to six or eight a month for the A330 over the next couple of years although Airbus has said it would seek to keep production levels fairly stable through the transition to the new version.
A spokesman said the cut in production would not result in job losses because the group is also ramping up production of the A350, which is due to enter service this year with launch customer Qatar Airways.
"With the recent commercial success we've seen following the launch of the A330neo, in addition to the new 242 tonne weight variant and the A330 optimised for regional routes, we are confident we will sustain a steady production towards the A330neo ramp-up period," Tom Williams, Airbus executive vice president programmes, said in a statement on Friday.
