The pilot reported that while taxing for takeoff, he observed a skip loader on the immediate left edge of the taxiway and noted there was sufficient clearance to avoid it. However, during the taxi, his attention was distracted by setting up the GPS for the flight, and the airplane drifted left, and subsequently struck the skip loader.

The right horizontal stabilizer was substantially damaged.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
