NTSB Factual Report

The flight instructor reported that he was taxiing from the runway to the customs area located on the northern side of the airport, which required the airplane to taxi on a road between the runway and the US Customs facility. The airplane's right wing struck a sign post on the right side of the road. The sign post dented the leading edge and bent internal wing ribs. The pilot reported no preimpact mechanical malfunctions or failures that would have precluded normal flight.

NTSB Probable Cause

The pilot's failure to maintain clearance from a pole.
