Narrative:
During aircraft clean-up, after takeoff the #2 leading edge slat did not full retract. Cycling the flap handle retracted the slat. Soon after, an F/a said a passenger noticed fluid streaming from the left wing and I verified that the #1 (left wing) fuel quantity gauge was decreasing at a higher rate than normal. The captain told me to inspect the wind, and indeed, I found that fuel was leaking from the leading edge of the left wing. At the time we were approximately 8000 pounds over maximum landing weight and had a significant wing fuel imbalance. The captain advised ATC that we would need to dump. We dumped approximately 10000# of fuel, to gain wing balance and decrease gross weight, then landed on runway 31R at dfw. After landing, we immediately shut down the #1 engine. After inspection by the fire department, we shut down the remaining engines and deplaned the passenger through the aft air stairs. The captain and I worked all coordination with ATC and performed all corrective action, while the first officer maintained aircraft control. The crew coordination (cockpit and cabin) seemed to go very smoothly. The leading edge slat had a bolt loose in the track fairing, and when the slats were retracted the bolt was pushed through a spar and fuel flowed out the resulting hole. We did not know if the incident was a result of cycling flaps or if it happened on the initial retraction, but next time I'll request to visually inspect the wing and ask the pilots not to be so set on having a clean confign. Callback conversation with reporter revealed the following: reporter had very little to add. He has heard nothing further about the incident. He said that it did not take long at all to dump until the wing tank weights were equalized. He also added that passenger reaction was very good and they remained calm throughout.

Title: LGT RETURN LAND DFW BECAUSE OF FUEL LEAK FROM PUNCTURED WING TANK.
Narrative: DURING ACFT CLEAN-UP, AFTER TKOF THE #2 LEADING EDGE SLAT DID NOT FULL RETRACT. CYCLING THE FLAP HANDLE RETRACTED THE SLAT. SOON AFTER, AN F/A SAID A PAX NOTICED FLUID STREAMING FROM THE LEFT WING AND I VERIFIED THAT THE #1 (LEFT WING) FUEL QUANTITY GAUGE WAS DECREASING AT A HIGHER RATE THAN NORMAL. THE CAPT TOLD ME TO INSPECT THE WIND, AND INDEED, I FOUND THAT FUEL WAS LEAKING FROM THE LEADING EDGE OF THE LEFT WING. AT THE TIME WE WERE APPROX 8000 LBS OVER MAX LNDG WT AND HAD A SIGNIFICANT WING FUEL IMBALANCE. THE CAPT ADVISED ATC THAT WE WOULD NEED TO DUMP. WE DUMPED APPROX 10000# OF FUEL, TO GAIN WING BAL AND DECREASE GROSS WT, THEN LANDED ON RWY 31R AT DFW. AFTER LNDG, WE IMMEDIATELY SHUT DOWN THE #1 ENG. AFTER INSPECTION BY THE FIRE DEPT, WE SHUT DOWN THE REMAINING ENGS AND DEPLANED THE PAX THROUGH THE AFT AIR STAIRS. THE CAPT AND I WORKED ALL COORD WITH ATC AND PERFORMED ALL CORRECTIVE ACTION, WHILE THE F/O MAINTAINED ACFT CTL. THE CREW COORD (COCKPIT AND CABIN) SEEMED TO GO VERY SMOOTHLY. THE LEADING EDGE SLAT HAD A BOLT LOOSE IN THE TRACK FAIRING, AND WHEN THE SLATS WERE RETRACTED THE BOLT WAS PUSHED THROUGH A SPAR AND FUEL FLOWED OUT THE RESULTING HOLE. WE DID NOT KNOW IF THE INCIDENT WAS A RESULT OF CYCLING FLAPS OR IF IT HAPPENED ON THE INITIAL RETRACTION, BUT NEXT TIME I'LL REQUEST TO VISUALLY INSPECT THE WING AND ASK THE PLTS NOT TO BE SO SET ON HAVING A CLEAN CONFIGN. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR HAD VERY LITTLE TO ADD. HE HAS HEARD NOTHING FURTHER ABOUT THE INCIDENT. HE SAID THAT IT DID NOT TAKE LONG AT ALL TO DUMP UNTIL THE WING TANK WTS WERE EQUALIZED. HE ALSO ADDED THAT PAX REACTION WAS VERY GOOD AND THEY REMAINED CALM THROUGHOUT.
