A Cathay Pacific Airways Airbus A330 turned back to Singapore Changi Airport on 16 May after a stall warning from one of its Rolls-Royce Trent 700 engines.
Cathay's flight crew shut down the no. 2 engine after receiving the alert, said the Oneworld carrier. The A330, which had departed Singapore for Jakarta at 00:54, landed back at Changi at 01:57 without incident.
The airline and Rolls-Royce are investigating the incident, said Cathay.
"The 136 passengers on the A330 were accommodated in hotels, and most were transferred to other flights later this morning," it added.
