A SEVERE VIBRATION DEVELOPED AS THE OUTER PORTION OF THE RIGHT RUDDERVATOR AND THE COUNTER WEIGHT FOR THE LEFT RUDDERVATOR SEPARATED FROM THE AIRFRAME ON THE DOWNWIND LEG AT AN ESTIMATED 155 MPH. TURBULENCE WAS NOT ENCOUNTERED AT ANY TIME DURING THE DESCENT OR THE APPROACH. THE PILOT CLOSED THE THROTTLE AND EXTENDED THE LANDING IN AN ATTEMPT TO SLOW DOWN THE AIRPLANE. AN UNEVENTFUL LANDING WAS MADE AT THE INTENDED AIRPORT. EXAMINATION OF THE RUDDERVATORS REVEALED THAT BOTH RUDDERVATORS WERE OUT OF BALANCE DUE TO A COMBINATION OF UNAUTHORIZED SHEET METAL REPAIRS, IMPROPER PAINT APPLICATION TECHNIQUES, AND THE USE OF A LOCALLY MANUFACTURED COUNTER WEIGHT.
Probable Cause: THE INFLIGHT SEPARATION OF THE RUDDERVATOR AS RESULT OF IMPROPER BALANCING.
