    Air India 787 crashes on take off

    I love when the lawyers get involved.... (from the datasheet that MintJulep posted):

    Air India 787 crashes on take off

    The report noted that on 737's there was an AD where apparently some of the switches did NOT have the "pull switch out" locking feature. The report speculates that a similar model switch is used on the 787, so did these switches actually have the locking feature? Specifically, this paragraph:

    Well, if something fell on the switches and cut off the fuel and I was the pilot, I would definitely reach down and try to re-light the engines... So, that would explain the "both directions" part.

    Here's another possibility: what if something fell on the switches and flipped them off? (I know they are supposed to lock in place, but again there was a comment in the report that does raise questions on whether the locking worked). I seem to recall a crash of a helicopter a few years ago...

    Air India 787 crashes on take off

    Now, the question becomes: Did the switches get PHYSICALLY turned off, or was there a wiring fault or electronics fault that mis-detected the switch positions? Also interesting that there was a Cat C MEL for "Core Network" active at the time. I wonder what that was about.... They also noted...

    Electric car ship fire.

    I thought I read somewhere that it sank in 16,000 feet of water. If that's the case, that's deeper than the Titanic. I doubt a salvage would be possible.

    On Airbus, the thrust levers do not move by order of the computer (not sure on 787 though). On the airbus, the thrust lever setting is more of a "thrust limit" most of the time, when AutoThrust is enabled. (but moving to the full throttle position, called TOGA, will force full throttle...

    I'm not familiar with the 787, but with Airbus, those switches are used for the normal startup of the engines and also for the normal shutdown. Think of them as an "engine on-off switch." Internally, those switches send commands to the computer to perform a sequence of events, so it's not just...

    The Airbus design is almost identical to that. But you can't just move those switches. You have to pull up on them to move them.

    Air India 787 crashes on take off

    The counter rollover bugs mentioned just shock me. I work in lifecycle maintenance (bug fixes) for enterprise-level networking hardware and we have had similar bugs in our code, over the years. We used to have our equipment starting acting "strangely" and even crashing if it was not rebooted...

    That just seems so unlikely. The gear is located on the front panel, left and above the throttles. Flaps are along side the throttles, to the right. Completely different action needed to operate them. Shaped differently. I'd be shocked if the PNF could get that reversed....

    Airbus models are almost the exact same layout.

    Air India 787 crashes on take off

    Assuming the crash didn't move things, that doesn't look like much flaps. Maybe 5 degrees?
