Plane fell 13,000 feet

Singapore Airlines is investigating how one of its jets suffered a loss of power in both of its engines over the weekend, falling 13,000 feet (3,962 metres) before regaining altitude en route from Singapore to Shanghai in China.

The Airbus A330-300 was carrying 182 passengers and 12 crew when the incident occurred on Saturday, the airline said in a statement. The jet lost power in both engines after hitting bad weather 3.5 hours into the flight. Power was restored after “the pilots followed operational procedures to restore normal operation of the engines”, the statement said.

Data from FlightRadar24.com and a report in the Aviation Herald revealed the plane was cruising at 39,000ft (11,887m), about 260km(162 miles) from Hong Kong, when both Rolls-Royce Trent 772 engines stopped working. The jet dropped to 26,000 feet (7,925m) before power was restored, and climbed back to 31,200 feet (9,510m), landing in Shanghai about 1 hour, 40 minutes later, the report said.
