Narrative:
The pilot was performing touch-and-go takeoffs and landings in the airport traffic pattern. After touching down, the pilot retracted the flaps and advanced both throttles to takeoff power. Shortly thereafter, he felt the airplane yaw to the right, observed an overboost indicator light for the right engine, and the airplane exited the right side of the runway. The pilot said that once the airplane was in the grass, he regained control of the airplane and reduced both engines to idle power; however, the airplane impacted the edge of a crossing taxiway and briefly became airborne before landing on the opposite side of the taxiway, resulting in substantial damage.
Postaccident examination of the airplane did not reveal any evidence of any preexisting mechanical malfunction of the engines or turbocharger systems that would have precluded normal operation. The circumstances of the accident are consistent with the pilot's failure to maintain directional control following an inadvertent overboost of the right engine during takeoff. 

Probable Cause: The pilot's failure to maintain directional control during takeoff following an overboost of the right engine during takeoff.
