tot lift dumper only deploy right after tyre touch runway?

well im no pilot or aviation folks, just reading the report for funsies.
the report conclusion & appendix do say primary cause is pilot error. report also say Pilot is not sitting on the pilot seat (instead he seat on the co-pilot's seat, while the co-pilot sitting on the pilot's seat), both are not sufficiently experienced for this aircraft model. SIC is second-in-command, referring to the co-pilot, and the co-pilot seems to be the one controlling the plane.
primary cause: SIC switched on lift dump during landing approach, lost altitude
additional findings; insufficient crew training

reading further on the report amendments section can see the company did tried to deflect/argue that it's not company's fault

Betul, I watched too many Aircrash investigation in Nat Geo to understand this

pilot noob

tak baik bang.

from google  "A lift-dump system, designed for activation once the wheels are on the ground, makes braking more effective."

so sic and pic baru unlock, tetiba malfunction and terus activate?

Shit they were alive till the end

Thought would have blacked out

RIP

If these people jumped right before impact, maybe can survive

last recorded transcripts

Report says "no pre-impact failures or malfunctions of the aircraft flight controls."

Most likely event was this:
"The accident resulted from a misunderstood checklist item, leading to inadvertent ground spoiler deployment."

So suppose to unlock but not extend it but someone (high probability) went and extend it.

Salahan manufacturer. If WOW sensor detects aircraft still in the air, there should be a logic to prevent the lift dumper from being deployed. Such a basic safety net also dont have, better stop making an aircraft.
