There's concern within the aviation industry that widespread engine issues plaguing dozens of Boeing Dreamliner aircraft around the world may extend much further than first thought.
Until now, the engine issue has been limited to a certain type of Rolls-Royce engine, only used on Dreamliner aircraft, including those owned by Air New Zealand.

However, an emergency landing in Boston yesterday has sparked fears the issue may not just be limited to Dreamliners.
The captain of an Iberian Airlines flight from New York to Madrid declared emergency after one of the aircraft's engines powered down, causing the flight to turn around and land in Boston.
The aircraft was an Airbus A350.
This latest incident has increased fears that problems with the Trent 1000 engines made for Boeing's Dreamliners could now extend to the Trent XWB engines that have been made specifically for Airbus A350 aircraft. Rolls-Royce has previously ruled out this possibility.
The engine issues have caused flight cancellations and delays for months for many airlines around the world and have reportedly cost the industry billions of dollars.
Rolls-Royce's share price had its biggest drop in a year following the Airbus A350 news.
