Narrative:

After fueling, I checked both fuel caps and found them secure. After takeoff, the tower advised that fuel was coming out of the right wing of the aircraft. I asked for a return to the airport and was advised to contact approach control. Approach control vectored me for an ILS 14 approach which was completed uneventfully. After landing, an inspection revealed that the right fuel cap had become dislodged and was hanging by its lanyard. No damage was found. I suspect that the lanyard was caught under the cap and prevented it from being securely seated, even though it appeared to be secure. During the return to the airport, I transferred fuel from the fuselage tank to the wings as a precaution. When I filled out the load manifest for the next takeoff, I forgot to indicate that there was only 600 pounds in the fuselage tank, instead of 1300 pounds. A corrected load manifest was completed the next day in accordance with the company operations manual.

Original NASA ASRS Text

Title: TURBOJET SMT HAS TO RETURN LAND DUE TO FUEL BEING LOST FROM AN UNCAPPED FUEL TANK.

Narrative: AFTER FUELING, I CHKED BOTH FUEL CAPS AND FOUND THEM SECURE. AFTER TKOF, THE TWR ADVISED THAT FUEL WAS COMING OUT OF THE R WING OF THE ACFT. I ASKED FOR A RETURN TO THE ARPT AND WAS ADVISED TO CONTACT APCH CTL. APCH CTL VECTORED ME FOR AN ILS 14 APCH WHICH WAS COMPLETED UNEVENTFULLY. AFTER LNDG, AN INSPECTION REVEALED THAT THE R FUEL CAP HAD BECOME DISLODGED AND WAS HANGING BY ITS LANYARD. NO DAMAGE WAS FOUND. I SUSPECT THAT THE LANYARD WAS CAUGHT UNDER THE CAP AND PREVENTED IT FROM BEING SECURELY SEATED, EVEN THOUGH IT APPEARED TO BE SECURE. DURING THE RETURN TO THE ARPT, I TRANSFERRED FUEL FROM THE FUSELAGE TANK TO THE WINGS AS A PRECAUTION. WHEN I FILLED OUT THE LOAD MANIFEST FOR THE NEXT TKOF, I FORGOT TO INDICATE THAT THERE WAS ONLY 600 LBS IN THE FUSELAGE TANK, INSTEAD OF 1300 LBS. A CORRECTED LOAD MANIFEST WAS COMPLETED THE NEXT DAY IN ACCORDANCE WITH THE COMPANY OPS MANUAL.
