Earlier post showed the " not ready for T/O" config warning.. Wondering, is it possible for it to test OK but not function properly? Never flown TU, so I'm not familiar with their procedures in that regard. Wondering perhaps if this aircraft might not have been configured in the first place... and perhaps the warning systems weren't functioning properly. It might explain the "flaps" comment previous pages if, say, they reached up to raise the gear and saw the flap lever incorrectly positioned....
I'm wondering if the flight profile here might be similar to the Northwest DC9 in Romulus Michigan...
