A Singapore Airlines (SIA) Airbus A380's No 3 Rolls-Royce Trent 900 engine was shut down during a Singapore-Frankfurt flight after the powerplant suffered an engine surge.
The incident occurred nearly 3h into the flight on 27 March, SIA says in a statement.
The aircraft, registration 9V-SKG, returned safely to Singapore where all 430 passengers as well as the crew disembarked without incident.
"We are looking into the incident and the engine will undergo thorough inspections in consultation with Rolls-Royce," says the carrier. "The crew reported an engine surge in the No 3 engine and the engine was shut down. The aircraft is capable of flying safely on three engines and at no time was the safety of our customers and crew compromised."
An aircraft change was carried out and the passengers have re-embarked for Frankfurt.
On 27 July, SIA said it changed a Trent 900 on another A380, registration 9V-SKH, after the powerplant suffered from "surge and high vibrations" 20min into a 25 July flight on the Singapore-Hong Kong route.
