The airplane returned from a local flight with substantial damage resulting from a crack through its vertical stabilizer spar. The airplane was used throughout its service life as a rental/flight training airplane. The airplane and vertical stabilizer accumulated a total time of 13,810 hours. According to maintenance personnel, the crack was not present during the airplane's last annual inspection, which was performed 7 hours before the flight. The crack is located approximately 6 inches above the base of the vertical stabilizer and extends horizontally approximately 1 1/2 inches from the right side of the stabilizer into the 3 1/2 inch spar. The maintenance personnel had installed a doubler at the root of the rudder as a preventative measure against skin cracks. Examination of the fracture surfaces were consistent with overstress fractures.
Probable Cause: The cracked vertical stabilizer and the unapproved maintenance modification to the rudder by company maintenance personnel.
