Pilot error does seem to be the logical conclusion here.
Checking the tech log once boarding would have been the first warning. There must have been a maint entry stating the work carried out overnight.
- check pressurization system
- normal cockpit preparation checklist
- mistaking the press warning for config warning.
For those blaming the company, lets take it one step further. Who is it that issued this company with an AOC and who is responsible for oversight (making sure they comply with the rules).
Maybe the Cypriot CAA should be the one being sued.
