Just after touchdown the aircraft rolled over a frost heave on the runway surface and began veering to the right. The pilot applied left brake and added power to the right engine but the aircraft continued going right until the right wing struck a hill adjacent to the right side of the runway. The aircraft came to rest in a ditch 110 degrees to the right of the landing runway heading. Examination of the right main landing gear tire revealed a large jagged opening in the sidewall which extended into the tread area of the tire. This opening matched one of the sides of a rock found in the vicinity of the frost heave.
The aircraft maintenance logbooks were reviewed and found to have no record of compliance with airworthiness directives.

Probable Cause:

directional control..not maintained..pilot in command
ground loop/swerve..uncontrolled..pilot in command
