Glad you spent your time fruitfully, no need to be sorry

 

1. Did the software have a known bug?

US aviation expert Mary Schiavo refers to a similar Boeing 787 incident involving All Nippon Airways in 2019, where both engines failed due to a software glitch — the aircraft's system falsely believed it was on the ground and cut fuel accordingly.

The Japanese airline could fortunately be towed whilst Air India had no chance- no altitude or time to recover.

 

2. Poor cockpit design 

Even if one of the pilots  operated the switch mid-take off, it may not have been deliberate.

 The stabilizer control switches — which the crew reported issues with earlier — are located next to the fuel cut-off switches. In the chaos of a stabilizer failure, a pilot could reach for one switch and hit the other.

 

3.  Regulators were warned  yet no inspections

Less than a month before the crash, the UK Civil Aviation Authority issued a warning over fuel shutoff valve issues on Boeing aircraft, including the 787.

The fuel control system had shown signs of potential failure across multiple models, however Air India didn't check the locking mechanism of the AI171’s fuel switch because a 2018 FAA advisory about the component was only that -advisory, not compulsory.

 

 

 

 

 

 

 

If you want to go with speculation against already published information then, up to you.

Maybe difficult to do if the GPU socket fault is still sensing the GPU?

 

Another report says it takes many seconds for the re-engagement of the fuel supply process to fully engage and gain a fuel flow after the switch to re-engage the fuel supply has been activated.

      From the report, it took only a second to shut down the second engine's fuel after the first one was cutoff--that seems like an easy procedure and not what some posted when the accident first happened.  Anything that easy could be done by mistake.

     Whether down by accident or on purpose, something so critical should have some sort of warning before it is allowed when it is done in flight.  This should be especially true if the first engine's fuel has already been turned off.  There should be some sort of prompt first--do you really want to do this? The first engine is already off.  Hmm?  That's going to leave you with no engines running--sure you still want to do this?

Yes, everyone with a YouTube channel is an expert and knows what they're talking about. 555. The last place to look for accuracy, well second last after TikTok.

France news 2 days ago, an active captain flying these planes said it was impossible to make a false move/mistake. To change the switch from on to off, one has to LIFT the switch first. It’s a safety action to stop a captain doing it by mistake. 

Today a report was published in the Wall Street Journal saying an outside source has heard transcripts from the CVR saying the second officer was flying the 787 on takeoff, and as he lifted away he asked the Captain why had he turned off the fuel cut off switches.

It was released last week and I mentioned it on here last Thursday. The source was an NTSB member attending the investigation in India, The serious implications of the comments probably explain why the full CVR transcript was not released - I think they have the whole lot.
