Analysis

While receiving VFR traffic advisories at 10,500 ft the plt reported a total loss of power. The aircraft crashed in a wooded area 1/4 mile nw of the Charlottesville arpt while receiving radar vectors. Investigation revealed a failure of the throttle control linkage between the throttle and the variable absolute controller assembly due to progressive wear. The failure would have allowed the throttle plate to vibrate to the closed position. Further exam revealed that a wave washer was missing in the linkage assembly. The engine had been overhauled and the turbocharger replaced 24 and 12 months respectively prior to the accident.
