Ok then. So everyone checks their flight controls but how many check both ailerons when turning the control wheel both ways? I heard of a Conquest undertaking a post-maintenance check flight where the pilot discovered the ailerons had been mis-rigged and no matter which way the wheel was turned both went up. The aircraft had been checked 3 times before that flight including the pilot control check but all had looked to see the corresponding aileron was moving up as the wheel was turned in that direction and not that the other was down.
