Narrative:

First officer's turnaround preflight walkaround was accomplished while fueler was fueling aircraft up to 4600 pounds from arrival fuel of 1800 pounds. All checklists were accomplished. The fueling-on light was out. After takeoff, the flight attendant called the cockpit to say a passenger notified her that something was loose and hanging from the aircraft and banging around in the slipstream. We told her to go check visually and report back. She informed us that the fueling panel access door was open and the fuel cap was off and banging around. We returned to airport. I checked for damage and found none. Maintenance was called to inform no damage or problems with door and cap. They did so, resecured each item and addressed my write-up in the maintenance log.
