Generally sensible post, however, it is absolutely reasonable to ask whether pilot skill / training was a factor.
The LionAir pre accident crew defused the situation with the help of a jump seat pilot. Once they had the aircraft under control, they re-enabled electric trim only to discover it attempting to nose the plane down again, before disabling it again and flying manually to destination.
That crew defeated AoA-failure-induced MCAS twice, not once.
...snipped...
That one in bold and underlined meant:
1. The crews got lucky they found
temporary solution to their "STS running the opposite way" problem.
2. Then they realized they needed an electric motor to trim after all. So, they turned it back on.
3. When the "STS running the wrong way trouble" showed up again, they killed off the electric motor for good.
The crew DIDN'T actually perform the so-called "Runaway Trim NNC", otherwise they'd written about that on their log and/or the ASHOR. They didn't even mention about the stick shaker incident which had consumed their entire flight until they'd landed safely at destination.
As written on the preliminary accident report:
The mystery is the pilot
claimed they'd performed the "Runaway Trim NNC" to the Indonesian crash investigator when infact they'd just killed the motor directly without even following any known procedure. As explained here...
Page 20 "Preliminary Aircraft Accident Investigation Report" KNKT
When they declared that they performed three NNC's, including the Runaway Stabilizer one, to the investigator, they had just exaggerated some of their actions and/or had obscured certain details after the fact. Indeed, they conveniently omitted a very important fact: a dead head sitting on jumper seat had been the one suggesting to kill the trim motor during the cockpit's highly tense full-of-warning-and-alarm episode. We now know about this "dead head hero" because there was a leak from the media.
The Indonesian accident investigators need to get to the bottom of these discrepancies, among other things, before reaching their final conclusion within the next 3-4 months.
