I can see how the rudder trim was left full deflection, wouldn’t be impossible to not complete and return to normal during the preflight internal inspections. That said, it’s inexcusable for this not to have been picked up during the before take off checks, or even down the runway prior to V1 (or similar, I only have experience on B350). It’s a pretty important item in the before take off checks.
All true, but its inexcusable to accuse a dead man of this without justification. And there is none. For all we know, he did all the checklists perfectly & diligently. And the guy had 2400 hours on type. He wasn't a weekend warrior.
Has anyone noticed that the prelim report says that 10 deg flap was selected, yet the final report says zero degrees flap was selected. The report offers no explanation to reconcile this. It says that examination of the LEFT HAND motor shows the LH flap was retracted. The report says it is unable to identify the position of the RH flap.
Wouldn't the LH flap being retracted and the RH flap being 10 deg down produce the same sort of effect? Might it cause the pilot to wind in full LH rudder trim to help compensate?
