Investigator assessment
Analysis narrative
The pilot of the airplane reported that while taxiing for departure he reached over to enter navigation information into the GPS, which was mounted on the right-side control yoke. While moving his hand back to the left side yoke, he inadvertently advanced the throttle forward. Subsequently, the airplane accelerated forward and impacted a hangar, which resulted in substantial damage to the engine mount. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
