So far, at least according to reports, only on RR powerplants. Hmmmmmm
I wonder if we will hear about any problems with the other powerplant options.
Powerplant (777-200) two Pratt & Whitney PW4077 turbofans
or two Rolls-Royce Trent 877 turbofans
or two General Electric GE90-77B turbofans
(777-200ER) two Pratt & Whitney PW4084/PW4090 turbofans
or two Rolls-Royce Trent 884/892/895 turbofans
or two General Electric GE90-85B/92B/94B turbofans
(777-200LR) two General Electric GE90-110B1 turbofans
(777-300) two Pratt & Whitney PW4098 turbofans
or two Rolls-Royce Trent 892 turbofans
(777-300ER) two General Electric GE90-115B turbofans

As has been said here before, don't forget that to all intents and purposes it's two engines flying in close formation...................
Hmm how does the saying go, once is an incident, twice a coincidence, thrice???????????
Worrying for both operators, PAX and RR I would imagine.

Ooops...

Sadly it's not true. Many systems are identical but paired, a few are much closer to each other than even the manufacturer believed...
Statistics? (re LHR incident)
Either it was a long shot coincidence losing both (assuming losing one is not a regular occurrence!)
or losing both is a different problem all together,
or It is one problem that can affect one or both engines.
There can't be many places to look for the source of a problem like that ... Perhaps the approach configuration/conditions ...
Puzzling. But I'm not an expert in how things go wrong.

Pilot error
I'm told the FO had his left arm on the autothrottle as he was holding the speed brake lever. This prevented the throttle from moving. No similarity with BA. This is standard AA procedure.
aarboy
That would have to be some strangely configured arm that guy has. He'd probably be able to scratch his balls and pick his nose at the same time whilst playing the star spangled banner on a picollo, with a weapon like that.

The FO has to reach over the throttles in order to reach the speed brake handle. Not only is it possible to interfere with auto-throttle movement, it's very easy to do and HAS HAPPENED numerous times before...
Usually the FO says, "Oops. Did I do that?"
After BA, they say, "Argh! Engine Failure! Engine Failure!"

Got a mate who is an engineer at an overseas station, he recalled recently a story of a Continental 777 a few years ago, that whilst on approach, one of the engines had shut itself down! Despite checks - no fault found!
