An Air New Zealand Flight NZ99 returned to airport after one of its engine performed abnormally after take off on Tuesday.

The Boeing 787-9 with registration ZK-NZE was climbing after departing from Auckland to Tokyo when the crew were alerted to abnormal indications on one of the two Rolls Royce Trent 1000 engines.

Onboard passengers reported the aircraft began to shake violently, clunking sounds, and electrical power went temporarily out.

The crew shut the suspected engine down and returned back to Auckland. The aircraft landed safely on single engine power without any further issues after 50 minutes.

Air New Zealand operated 9 Boeing 787s and have 4 more on order.

This is the second engine vibration incident involving the Rolls Royce Trent series engines in 2017, after an Air Asia A330 returned to base after severe inflight shaking in August 2017.
