A BE90 returned for a precautionary landing when the tower advised of 'smoke' coming from the right engine. Inspection determined the 'smoke' was actually fuel escaping from an improperly secured auxiliary tank fuel cap which had come loose in flight.

Narrative:
Aircraft was fueled; including fuel in auxiliary tanks. Upon takeoff; tower advised that 'smoke' was coming from right engine. I entered a right-hand pattern for precautionary landing. After shutdown; it was discovered that the right auxiliary tank fuel cap was hanging to the aircraft by its lanyard i.e. Not secured to the fuel tank opening. Auxiliary tank caps on king airs are not reachable unless one is on a ladder; so visual inspections for proper closure is probably the norm. Not good enough for this flight; even though fueler had also visually 'confirmed' that the cap was secure.

Narrative: Aircraft was fueled; including fuel in AUX tanks. Upon takeoff; Tower advised that 'smoke' was coming from right engine. I entered a right-hand pattern for precautionary landing. After shutdown; it was discovered that the right AUX tank fuel cap was hanging to the aircraft by its lanyard i.e. not secured to the fuel tank opening. AUX tank caps on King Airs are not reachable unless one is on a ladder; so visual inspections for proper closure is probably the norm. Not good enough for this flight; even though fueler had also visually 'confirmed' that the cap was secure.
