Analysis

The plt reported a partial loss of pwr occurred momentarily before liftoff. The takeoff was continued and once airborne the pwr loss reoccurred. The load was dumped, however, the acft impacted trees aprx 1 mile from the arpt as sufficient alt could not be maintained. Post accident inspection revealed the #2 and #8 cylinder intake valves were tuliped and would not close. The #2, #6 and #8 outlet tower blocks on the magneto were crossfiring which resulted in pre-ignition to those cylinders.
