Turkish Casa crossed controls
 

Read in Flight mag:
"EADS Casa has revealed that the Casa CN-235 transporter which fatally crasshed in Turkey during its first test flight off the turkish production line had its ailerons mis-rigged.All four crew died in the May 128 accident at Ankara's Akinci airport."

Apparently checks are still not performed correctly even by test pilots and quality controllers.
A second thought :Twasn'nt an A-320,so nobody cares here,and nobody has taken this to argument on the merits of independent side sticks.
