Recently two Air New Zealand flights using 787-9s had to return to Auckland after experiencing engine trouble. Here are two pictures of engine damage. More information here. It is not known what caused the damage. We understand certain parts have worn faster than expected.
Rolls-Royce advised us that this is “a fleetwide Trent 1000 issue, they just happen to be affected at the moment while we undertake proactive maintenance.” Rolls-Royce offered this statement: “We sincerely regret any disruption caused by our engine that our customer is experiencing and we are working together to minimise this impact and restore full flight operations as soon as possible. It’s not uncommon for long-term engine programmes to experience technical issues during their life and we manage them through proactive maintenance. We have a clear service management plan in place with all operators to undertake this work and minimise disruption. This is the continuation of work which started last year to upgrade Trent 1000 engines to the latest standard. We are in constant dialogue with our industry regulators and they support the proactive service management plan we have created with our customers.”
