“After taking off for Chicago last week, the aircraft returned to Auckland due to a fuel discrepancy discovered just over an hour into the flight. A component of the engine is unable to be serviced in Auckland, so as a proactive measure, the engine is being changed. We expect the aircraft to return to service on Friday.”
The original aircraft for NZ946 from Auckland to Rarotonga sustained a lightning strike, which required inspection.
“Lightning strikes are not uncommon, and this is standard procedure when they do occur.”
Following a Herald report on the downgrade, other passengers have been in contact about the same issue - one from a Sydney-Auckland flight last week, one from the same route in early May and another from a Brisbane-Sydney flight in March. Those who had flights changed at short notice were offered $350 to compensate and have been offered refunds of the difference between the fares.
Daley said aircraft changes take place from time to time to protect the airline’s operating schedule.
“This is not a systemic problem. However, we understand aircraft changes can be inconvenient for customers and we thank them for their understanding in these circumstances,” he said.
The grounded plane is four years old.
Eight days ago, an Air NZ Dreamliner three hours into a flight to Tokyo had to turn back after its windscreen was damaged and it had to return for repairs.
The airline has 14 Boeing 787-9s, the first of which was delivered in 2014. It is due to take delivery of new Dreamliners to boost its fleet at the end of next year.
The Dreamliner problems come as some of the engines on the airline’s A320neos and A321neos are grounded because of a global issue with services of their Pratt and Whitney engines.
