ANZ Suffers Trent 1000 Problems

Engines power the carrier's Boeing 787-9 fleet.

Deliveries of the Trent 1000 TEN can’t come quickly enough for Air New Zealand (ANZ), one of the inaugural operators of Rolls-Royce’s updated engine for the Boeing 787 family.

Today (Dec. 7) the airline announced several cancellations and delays owing to earlier-than-expected maintenance for its older Trent 1000 engines.

A lack of spare engines exacerbated the problem, and ANZ is now seeking replacement aircraft to fill the capacity gap.

MRO demand for the Trent 1000 will ramp up quickly towards the end of this decade. Aftermarket revenue is forecast to climb to about $150 million in 2018 and $420 million in 2020. In 2025, the Trent 1000 MRO market is expected to top $815 million, accounting for more than 20% of the total 10-year demand of $3.8 billion, Aviation Week figures show.

ANZ took its first 787-9 in 2014 and now operates 11 of the type.

In 2016, following significant issues with Trent 1000 engines on Japanese carrier ANA’s 787 aircraft, New Zealand’s flag carrier said it was less susceptible to the premature blade wear that ANA suffered, since the latter carrier used its 787s for shorter, cycle-heavy operations, whereas ANZ deployed its 787 on long-haul services.

ANZ also said it was taking “pro-active” steps in conjunction with the manufacturer to avoid similar problems for its engines.

According to the carrier, Rolls-Royce was able to use aircraft performance data “to predict, with a high degree of accuracy, which engines are likely to experience this issue”.

The airline hasn’t disclosed why the engines now need maintenance, but the issue again highlights the importance of Trent 1000 TEN after three prior iterations of the Trent 1000.

The TEN represents the engine family’s most significant improvement. It incorporates 70-75% new parts compared with earlier versions of the Trent 1000, as well as advanced technologies proven on the Trent XWB family.

It entered service in November 2017.
