Circumstances:
The pilot stated that during takeoff roll he experienced a power surge but the engine did not quit. He aborted the takeoff by reducing power on both engines and applying brakes. This resulted in the aircraft swerving off the right side of the runway, rolling thru the grass and striking a culvert which separated the landing gear. Wreckage examination revealed: both throttles at idle, mixture and prop controls were full forward and full rich and high rpm on respective engine controls. All cables attaching hardware was intact.
