## Discrepancy

ENGINE OVERSPED IN CRUISE FLIGHT AT 6,500 FEET.  MAXIMUM OVERSPEED WITNESSED WAS 3,500 RPM.  AIRCRAFT LANDED AT FIRST SUITABLE AIRFIELD.

IT APPEARED THE BREAK IN THE CAM ORIGINATED FROM A CRACK AT THE WOODRUF KEY SLOT.  NOTE:  ENGINE WAS OVERHAULED 550 HOURS AGO DUE TO SUDDEN STOPPAGE (GEAR -UP LANDING).
