Last night another Air New Zealand 787, headed to Buenos Aires, Argentina, experienced an engine issue shortly after leaving Auckland and was also forced to return.
"Customers on this service are now booked to travel on an alternative service today".
Air New Zealand is cancelling some flights and retiming others due to maintenance requirements on the Rolls-Royce Trent 1000 engines that power its Boeing 787-9 fleet.
The pilot elected to shut down one of the plane's engines as a precaution during flight NZ99 to Narita, Tokyo.
"In addition to these changes, Air New Zealand is focused on securing replacement aircraft capacity".
The issue stemmed from corrosion and cracking of turbine blades and forced Rolls-Royce to fit new blades on all the 787s operated by Japan's largest airline. "We finalised the schedule changes for Friday through to Sunday early [Thursday] afternoon and began the process of contacting customers".
"Rolls-Royce does not have any replacement engines available while this maintenance work is undertaken which means some schedule changes are unavoidable".
"At this stage our investigation team is satisfied that all parties are doing the right things to ensure the continuing safety of the travelling public".
The Star Alliance carrier says that following two recent events, Rolls-Royce has advised that its fleet's Trent 1000 engines "require maintenance sooner than previously indicated".
The Trent 1000 engine has had a number of technical hitches, which the manufacturer has been working hard to resolve, with a wide range of operators in recent years. Japanese airline ANA first reported issues with Trent 100s in the summer of 2016. Both airlines took aircraft out service for urgent maintenance, causing hundreds of flight cancellations.
