Rolls-Royce suffers fresh wave of troubles with Dreamliner engines

Singapore will use and Boeing 777s on new service

The engine issues both happened on Boeing 787 Dreamliner planes flying out of Auckland bound for global destinations.

Both incidents involved the engines during climb on takeoff from Auckland, forcing them to turn back.

And on Tuesday, the airline's flight to Tokyo Narita also returned to Auckland due to what the TAIC again said were "abnormal indications on one of the engines".

Singapore Airlines will operate a mixture of Airbus A380s and Boeing 777-300ERs on the service, while Air New Zealand will use a newly configured 787-9 aircraft.

"In addition to these changes, Air New Zealand is focused on securing replacement aircraft capacity".

Singapore Airlines (SIA) and Air New Zealand on Thursday said they will jointly launch a third daily flight between Singapore and Auckland, boosting capacity on the route by 40 per cent and adding more than 165,000 seats annually between the two cities.

"Rolls-Royce does not have any replacement engines available while this maintenance work is undertaken which means some schedule changes are unavoidable".

Customers affected by these changes will be proactively contacted with new travel information.

Commenters on the Aviation Herald website said the aircraft flying as NZ99 was the first pressed into service by Air NZ - two of its Dreamliners were actually built earlier but held back by Boeing for its certification programme.

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. The problem was thought to relate to blades in the turbine corroding far earlier than expected, resulting in the engines being shut down. Both airlines took aircraft out service for urgent maintenance, causing hundreds of flight cancellations. "This is the continuation of work which started past year to upgrade Trent 1000 engines to the latest standard".
