Narrative:

I left lee's summit airport around XA00, flew south 10-15 mi. Called approach for a practice ILS at gvw and was given a heading of 210 degrees. Shortly thereafter the engine misfired. I tried carburetor heat with no permanent effect. I decided to make a precautionary landing and did so in an open field without incident. Engine continued to run until mixture control was pulled out. Upon examination of fuel caps the left one was found to be loose and a lot of fuel stain was found on the wing. Also sump valve on right wing was leaking a drop at a time and had been for some time. I believe the fuel starvation was due to the leaking sump valve and loose fuel cap. The aircraft was fueled after previous flight and stored in a locked hangar. I had the airport bring out some fuel and put 10 gallons in the left tank and 5 gallons in the right tank. I then flew back to airport on the left tank without incident. My passenger who also is a flight instructor assisted me in the off airport landing. Supplemental information from acn 392105: though I was not the PIC, I am a flight instructor, and was asked to go along as a safety pilot with the pilot. After some 30-45 mins of flight, the engine misfired. After an attempt to keep the engine running, the pilot said 'I think we are out of fuel.' at this time a precautionary landing was made while we still had some power. The engine was stopped by closing the mixture control. I got out of the aircraft and checked the fuel caps. I found the right one was loose and the top of the wing was covered with fuel. I called the airport and had some fuel brought to us. The aircraft had a leaking fuel drain on the right tank for some time, only a slow drip. This, along with the loose fuel cap caused the fuel loss.

Title: THE PLT OF A C182 MADE AN OFF ARPT LNDG WHEN THE ACFT RAN OUT OF FUEL. DURING THE AFTER LNDG INSPECTION SEVERAL FUEL LEAKS WERE DISCOVERED.

Narrative: I LEFT LEE'S SUMMIT ARPT AROUND XA00, FLEW S 10-15 MI. CALLED APCH FOR A PRACTICE ILS AT GVW AND WAS GIVEN A HDG OF 210 DEGS. SHORTLY THEREAFTER THE ENG MISFIRED. I TRIED CARB HEAT WITH NO PERMANENT EFFECT. I DECIDED TO MAKE A PRECAUTIONARY LNDG AND DID SO IN AN OPEN FIELD WITHOUT INCIDENT. ENG CONTINUED TO RUN UNTIL MIXTURE CTL WAS PULLED OUT. UPON EXAMINATION OF FUEL CAPS THE L ONE WAS FOUND TO BE LOOSE AND A LOT OF FUEL STAIN WAS FOUND ON THE WING. ALSO SUMP VALVE ON R WING WAS LEAKING A DROP AT A TIME AND HAD BEEN FOR SOME TIME. I BELIEVE THE FUEL STARVATION WAS DUE TO THE LEAKING SUMP VALVE AND LOOSE FUEL CAP. THE ACFT WAS FUELED AFTER PREVIOUS FLT AND STORED IN A LOCKED HANGAR. I HAD THE ARPT BRING OUT SOME FUEL AND PUT 10 GALLONS IN THE L TANK AND 5 GALLONS IN THE R TANK. I THEN FLEW BACK TO ARPT ON THE L TANK WITHOUT INCIDENT. MY PAX WHO ALSO IS A FLT INSTRUCTOR ASSISTED ME IN THE OFF ARPT LNDG. SUPPLEMENTAL INFO FROM ACN 392105: THOUGH I WAS NOT THE PIC, I AM A FLT INSTRUCTOR, AND WAS ASKED TO GO ALONG AS A SAFETY PLT WITH THE PLT. AFTER SOME 30-45 MINS OF FLT, THE ENG MISFIRED. AFTER AN ATTEMPT TO KEEP THE ENG RUNNING, THE PLT SAID 'I THINK WE ARE OUT OF FUEL.' AT THIS TIME A PRECAUTIONARY LNDG WAS MADE WHILE WE STILL HAD SOME PWR. THE ENG WAS STOPPED BY CLOSING THE MIXTURE CTL. I GOT OUT OF THE ACFT AND CHKED THE FUEL CAPS. I FOUND THE R ONE WAS LOOSE AND THE TOP OF THE WING WAS COVERED WITH FUEL. I CALLED THE ARPT AND HAD SOME FUEL BROUGHT TO US. THE ACFT HAD A LEAKING FUEL DRAIN ON THE R TANK FOR SOME TIME, ONLY A SLOW DRIP. THIS, ALONG WITH THE LOOSE FUEL CAP CAUSED THE FUEL LOSS.
