Or rather, as airworthy as any other MAX flying around.
Not sure why you're being downvoted, as I haven't seen any evidence linked contradicting what you said.

"not airworthy" means that it was unsafe.
It goes like this:
several flights report problem
maintenance "fixes" the problem
next flight reports that another, worse problem has appeared - bad enough that regulators have now said that the plane was "not airworthy" during this flight
maintenance "fixes" the problem
final flight impacts ocean at high speed
Your assertion is that since maintenance cleared the plane after the second fix, the plane must have been fine. To that, I point to the previous time maintenance cleared the plane, when it was demonstrably not fine.
> The chief executive officer of Lion Air, Edward Sirait, said the aircraft had a "technical issue" on Sunday night, but this had been addressed in accordance with maintenance manuals issued by the manufacturer. Engineers had declared that the aircraft was ready for takeoff on the morning of the accident
So you still haven't supported your extraordinary claim that the aircraft was:
> unsafe on takeoff.
In fact we know it was safe on takeoff.
