A Singapore Airlines Plane Lost Both Engines And Kept Flying

Flightradar24 is reporting that Singapore Airlines flight 836 from Singapore to Shanghai suffered a double engine failure yesterday at cruising altitude. The flight was operated by an Airbus A330-300, and apparently the plane dropped 13,000 feet before power returned:

The double engine failure happened while they were flying through the outflow of a huge storm:

Double engine failures are extremely rare, and immediately reminded me of British Airways flight 9, which was a 747 in that 1980s that lost all four engines due to an ash cloud:

Perhaps the most interesting part of the SQ836 situation is that the pilots decided to continue to Shanghai after restarting the engines, despite being really close to Hong Kong. Unless you’re 100% certain that the incident was isolated and couldn’t happen again (which is tough to do without a proper inspection/investigation), that’s not something you’d usually do.

While it doesn’t make sense to speculate, it will be really interesting to see what comes of this investigation. Hopefully the details are made public.

Fortunately this one ended well — thank goodness!

My guess is that pilots forgot to switch on the engine anti icing and therefore knew that it was safe to fly on to Shanghai after restarting engines and of course turning on the anti icing

Ice crystals from nearby storms can cause multiple engine power loss. Whilst there are anti-icing measures for ground operations, there are not for high altitude ice crystals on older engines like the Trent 700. Ice crystal ingestion can lead to ice build up on the engine compressor, leading to one of several outcomes - surge, flameout, or damage from ice release within the compressor. Might be an explanation for what happened.

I was on that flight.Plane didn't plunge,was bumpy and a few sudden drops but have had worse flying in rough weather.Could smell something like burning rubber or a burnt out clutch in the cabin.I knew then we had some issues,maybe a lightning strike or two,but the loss of two engines has freaked me out now.Can't believe they didn't divert somewhere on route,let alone turned the flight around at Shanghai with just two hours delay.Have bought mandatory lottery ticket.

The Daily Mail article has some good details. Singapore Airlines did state that both engines lost power, though one was revived almost immediately, and they were able to restart the second engine "by putting the aircraft into a controlled descent". I'm bothered by the continuation to the final destination. If you look at the wikipedia entry for glides, most have ended in crashes. Some required emergency landings, including the infamous Hudson River landing by Sullenberger in 2009. (Of course that one wasn't just loss of power, it was bird strike.) DM says the engines were inspected and the plane took off on it's next flight with only a 2 hour delay. Is 2 hours enough time to properly troubleshoot the problem?
