If it's got software, it's got bugs.

that's not a bug.

that's a feature.

Was this a malfunction of a safety function intended to prevent activation of TR in flight?

From one of the articles: "It’s worth noting that a bulletin was released by Boeing not so long ago to pilots and maintenance crew about the Thrust Control Malfunction Accommodation (TCMA) system, which prevents risk in an uncommanded high-thrust situation, stating that errors in the landing sequence could cause the system to activate. The errors include a combination of selecting full reverse too quickly before the aircraft has transitioned to ground mode followed by a quick deactivation of reverse thrust. Boeing advises not to apply full reverse too quickly in the bulletin."

A hundred thousand more lines of code should prevent this from reocurring.

Lets be honest. Bentwing is right. Pilot error. The odds of SIMULTANEOUS engine shut down at the exact moment RT is applied for any other reason are astronomical.

Just Boeing software in control of it?

It's called freedom of speech, mate...
Btw I thought Boeing was an aircraft manufacturer, in fact a good one (not the best one but a good one...) not just a company putting parts together without any quality responsibility over their planes as a whole product.
Thanks for letting me know.

You got stuck in 1970... or you meant "unable to fly Boeing planes > unable to fly Airbus planes?
Then you are right ;)

Well written software would capture the incident. To write it off as a "glitch", is the easy way for the software team to write it off as a anomaly, until it happens again. The answer lies in the code, and I doubt ANA wants to spend time finding the root cause, as that would require a lot of time and money, unless the code was written well.

It makes a lot of difference if they shutdown after touchdown, rather than on final. The article attached says they shutdown after touchdown. BIG Difference!!

That's a perfect example of brainless responses. See my last comment further on. At least I propose causes and why a 777 went down. It was proven to be a safety bug because the auto-throttles engaged simultaneously.

Question here and this is just a question or my thought. Could this be related to maybe fuel shut down on the engines. They say they just activated the reverse thrust could they system actually thought they shut the fuel cut off off and rolled the engines back.
bentwing60
bentwing60 2
The PF could have accidentally grabbed the fuel cutoff levers instead of the TR's and it gets real quiet real quick. OOps! My first thought william cause I did it once in an old straight wing Citation long ago and far away. The other guy just started grinnin. Maybe he did it once too.
williambaker08
william baker 1
Ya but they fact that they couldn’t get them restated has me confused. Could have happen and the software glitches they reset the computer during testing and found nothing wrong?

Someone said something about the British airways 777 flight 38 and to be honest this doesn’t sound like a fuel oil heat exchanger issuer or a loss of fuel.
bentwing60
bentwing60 2
They shut down at a very opportune time for this flight and I agree on the exchanger issue, but when they shut down at the same time I would rather see the cause be operator error, as opposed to computer glitches in flying computers. Hope to see the answer here at a future date. The one thing I can say for sure is that I am not surprised by the name attached to the squawk.
williambaker08
william baker 1
I hear ya there on the name. And all we can do is ask questions and think about what caused it. Doesn’t sound right that it happened as the reverse thrust was just activated. But time will tell what happen and also glad that nobody got hurt in this incident.

Would be pretty difficult to shut down the engines inadvertently in a 787. The thrust levers do not have a cutoff position. There are two individual switches (1 for each engine) that need to be activated and are separate from the thrust levers. You'd need both hands to shut down the two engines simultaneously.

Hmmm.....a 787 with just 118 passengers?
Thinking fuel like that BA 777 that glided into Heathrow with no engines.

Actually...... They never said it was fuel exhaustion, and as far as I can tell they never said it wasn't.

Has anyone seen it reported anywhere?



If it were fuel exhaustion that would explain why they found nothing wrong with the engines !!!

Wouldn't a solution to hitting the fuel cut off lever be to make it have a texture, so your figures can feel it's different from other levers? Sort of like those little bumps they put on the J an F keys on a keyboard.

The transport category jets I have flown all had one or more defining elements to prevent grabbing the wrong control in a moment of confussion. Some texture, most shape, and all with location. The fact remains, when the PF grabs the wrong thing in a brain dump, the deed is done and all the engineering in the world won't fix that. Don't know if that is the culprit here, hope to find out. Most pilots don't divulge their most egregious goofs at the bar, but you can learn a lot by reading the ASRS report summaries and while you won't know who they are, there are some pretty good tales on occasion.

The same thing happened to British Airways Boeing engines rolled back to flight idle on landing approach. Boeing has a software problem with the 787. It's time to do an extensive analysis of the software on both engines. There is a uniform fault.

Are you referring to the 777 landing LHR 2008? If so, that was an ice crystal issue in the fuel...

That was ba flight 36 and it was ice crystals thst plugger the fuel oil heat exchanger.

Aren't you supposed to shut off the engines after you land?

I heard that shutting down the engines just before landing on under booked Jumbos is one of the new fuel savings measures recommended by several airlines.
