Trent 1000-Suffering Air New Zealand Orders GEnx

If actions speak louder than words, Air New Zealand’s latest Boeing 787 order says a lot.

When engine problems disrupt operations, it is rare for airlines to publicly voice displeasure with the manufacturers. Instead, they talk about ongoing “cooperation” to resolve the matter, while pursuing compensation talks in private.

Often, even big problems won’t dissuade an airline from ordering more of the manufacturer’s equipment, since they are already committed to their existing fleets and have the support infrastructure in place for future purchases.

Air New Zealand, however, has evidently had its fill of setbacks from the Rolls-Royce Trent 1000, and has ordered the competing GEnx1-B to power its latest order for eight Boeing 787-10s.

The aircraft will replace eight 777-200s powered by Trent 800 engines, and will supplement the flag carrier’s existing fleet of 13 787-9s, which use the Trent 1000.

Air New Zealand was one of many international carriers forced to ground aircraft over Trent 1000 problems, which are estimated to have cost it about $25 million so far.

The airline might have hoped that engine issues were behind it as it began to take delivery of the new Trent 1000 TEN, a model that shares only 25% parts commonality with earlier builds, and was supposed to mark a clean break with mistakes of the past.

In April, unfortunately, Rolls-Royce announced an accelerated inspection program for high-pressure turbine (HPT) blades on the TEN, following an earlier communication to airlines that the engine’s HPT blades would not last as long as advertised.

“We sincerely regret the disruption this accelerated inspection regime will cause and we are doing everything we can to support our customers,” said Chis Cholerton, Rolls-Royce’s president, civil aerospace, in an apology issued to Boeing 787 operators.

Air New Zealand’s order for eight GEnx-powered 787-10s comes with 12 options and the right to swap orders for the smaller 787-9. First deliveries from the new order are scheduled for 2022.
