Narrative:

This was a part 91 repos flight from isp to ZZZ1 scheduled to depart approximately at XA30. At approximately XA00 I preflted the aircraft; in which time all the panels were secure and all fuel caps on and the fuel door closed and latched. The fueler showed up after preflight and topped off the aircraft. Both crew members were in the cockpit at the time of the refueling. The fueler for whatever reason finished fueling the aircraft; then forgot to replace the fuel cap on the single point refueling receptacle or close the door. He then drove off as if he had finished his job. Both crew members assumed he had done his job properly and continued with preflight duties. After becoming airborne; a low rumble could be heard outside the aircraft. The co-captain (sic) went back to investigate and we assumed the fueler had left the fuel door open. We returned immediately to isp and slowed the aircraft down to a safe speed to prevent any further damage. The remainder of the flight and landing were uneventful; but some minor damage was done to the leading edge of the aircraft and a side panel aft of the refueling door. The aircraft was inspected by maintenance and then returned to service and flew approximately 1 hour later. After engine shutdown; the fueler admitted to failing to secure the cap or door and was apologetic; but did not explain why he forgot.
