A Singapore Airlines passenger plane carrying 194 people dropped 13,000ft after both engines lost power in a “huge storm”.
The Airbus A330-300 was three and a half hours into its five-hour flight from Singapore to Shanghai when its Rolls-Royce Trent 772 engines failed at 39,000ft.
The pilots managed to restore power by putting the aircraft into a controlled descent to 26,000ft, before climbing again.
SQ836 continued normally to Shanghai and landed at 10.56pm local time on Saturday, Singapore Airlines said.
It said both engines were “thoroughly inspected” and “no anomalies” were detected. Aviation experts said it was a “very unusual occurrence” for both engines to lose power.
Singapore Airlines, Airbus and Rolls-Royce are investigating the incident.
Passengers appeared not to have posted about the incident on social media, meaning they may have been unaware of the engine problem.
