He landed fast at an arpt 12 nm away, travelled off the end of the rwy, and collided with bushes. Fuel imbalance was not a factor. A mechanic who repaired the acft reported that the pitot static system was partially blocked by contaminants. The rigging of the ailerons and flaps checked satisfactory.
