On collecting our PA31 G-PIZZ from its annual maintenance check , as I taxied away from the maintenance hangar I noticed that the control yokes ( without any pilot input) sat right "out" ie away from the coming and instruments where as previously as any PA31 driver will tell you they sit flush, ie "in" by the coming until aerodynamic speed is sufficient for the tail plane to start " flying" and they start to come out ( does that description make sense ??)
You cannot see the tail plane and elevators from the pilot seat.
In taxied back convinced something was wrong.
Very embarrassed engineers now set about now re-rigging the elevators correctly - they were crossed cables giving the opposite control to the input given....
