Boeing needs Joe Patroni. He's give her all she's got.

So, I suppose Calhoun can golden parachute into retirement now, very well rewarded for warming that seat. Same as Muilenburg.
Meanwhile McNerney, the man responsible for scrapping the Y1 737 replacement, costing Boeing its edge and bringing shame upon the brand, has slipped justice and is also enjoying his riches.
America, ladies and gentlemen....

Some further clues here:
Why do I think that a condition in which the pilot seat could unexpectedly and rapidly advance into the control column might be a prime candidate for a mandatory compliance airworthiness directive?
I realize that hindsight is 20/20, but why does foresight have to be -8 with astigmatism?...

The 787 has an additional seat track switch hidden under a plastic flap on the top of
the seat back. If that flap is missing or is stuck in the open position, I can easily see how a FA can inadvertently hit it while bracing a hand against the seat back. If this happened, I would expect an emergency AD requiring inspection of this flap guard.
In the longer-term, I would require a modification that disables this switch when the pilot is seated.

I think the field and avionics detection technology has allowed closer operations somewhat in the same way digital autoflight has allow RVSM. It's all about threading needles these days....

So this doesn't add up. Unless LATAM hasn't done a ODLF update in almost nine years! That's unpossible...
But while we're here:
Sudden, unrealistic drops in airspeed are considered unreliable by competent pilots. The first order of business is to cross-check and if all three are in agreement, declare unreliable airspeed (most likely pitot icing), maintain current pitch and power settings, and work the QRH. A competent pilot will not respond to this by making 'pilot control inputs that could exceed the structural capability of the airplane' (or stall it). After AF447, hopefully this routine is well-rehearsed.
I would be more concerned about sudden unrealistic (yet still ruled valid) drops in airspeed effecting the avionics and the autoflight and/or gust suppression. ...

But wasn’t that ‘bug’ also discovered many years ago? Hasn’t Boeing done anything to remove it? I mean, a vulnerability like that is not tolerable in anything you might want to call ‘airworthy’.
In the hands of a lesser crew… remember, a sudden loss of FCC’s caused (led to) the upset, stall and crash of an AirAsia A320....

The GCU bug was revealed in 2015. Boeing was already removing the bug for a software update. The AD had 30-day compliance. Is it possible for a LATAM 787 to be powered up for 287 days, with no compliance on the AD and no software updates in almost nine years?! If it is, I'm going to have to put them on my list....

AFAIK, there is no automated facility on the 787 with that kind of pitch (elevator, flaperons) authority other than the autopilot and the vertical gust suppression. It also gets airspeed from a synthetic airspeed algorithm, which, I suppose, could be effected by software vulnerabilities. The gust suppression is supposed to dampen turbulence upsets, not cause them, but perhaps a fault supplying data to this system is behind it. I'm expecting that, when we learn what caused this, it will be a deep dive into 787 system interdependencies. With very little technical documents available to the public, I'm looking forward to reading the report....

LATAM 787 Sudden Drop due to 'Technical Incident'
Hmmm...
https://avherald.com/h?article=51601631&opt=0
A violent upset with 12 passenger injuries. This is a post taken from Aviation Herald (no idea if it is valid)
That's not good.
There's a shade of the A330 upset incidents here. Those were caused by a hidden vulnerability to extremely rare ADIRU data spikes apparently the result of cosmic radiation, but the software was modified to prevent further occurrences. And I don't know if the 787 has a comparable pitch-lowering alpha protection function.
Whatever happened, it seems to be just as rare.

Ha! Have you ever noticed the braille elevator buttons in parking ramps?
BTW, the "I" in PILOT is missing a dot. In Braille, you dot your "i"s twice. I think it reads Pīlot Lounge....

I don't see age or cycles as a valid factor. These jets are supposed to be inspected and serviced regularly (and carefully!). I think what happened here could just as likely have happened to a 5-year-old airplane. Negligent maintenance doesn't take long to reveal itself. It's a lucky thing it didn't kill anyone.
I remember a story about a man who was killed by a semi-truck tire that had departed a long way off. He never even saw the truck. Some people just have a tire with their name on it....
