Narrative:

On flight from ft myers-page, fl, to houston, tx, stopped in pensacola (pns) for gas and lunch. Took on 40.2 gallons 100LL, tank appeared to be full, which should allow for 5 hours of operation. Filed IFR flight plan in the air with deridder, la, FSS after getting updated WX for houston. Flight plan activated near lafayette (lft), rted direct sabine VOR and gilco 1 arrival. While being radar vectored to andrau airpark (aap), noticed fuel pressure falling, switched on boost pump, then the engine quit. I switched tanks, engine restarted, but quit about 10 mins later at 3000 ft MSL in IMC. ATC vectored me toward aap. I broke out at 1700 ft MSL, but didn't feel I could make the airport, so I landed in a large field about 1-2 mi south of aap rather than chance gliding over the built-up residential area between this field and aap. Landing normal, no damage to aircraft or property. On inspection, tanks were empty. A known problem with these tanks is that they seep fuel along the top of the spar when full, but this has always been very minor. Gauges read lower than actual, so I was not concerned with low readings, and have always measured fuel burn by time. When in doubt, will refuel, reduce trip legs to 3 hours maximum.

Title: OFF ARPT EMER FORCED LNDG WHEN SMA SUFFERS FUEL EXHAUSTION.

Narrative: ON FLT FROM FT MYERS-PAGE, FL, TO HOUSTON, TX, STOPPED IN PENSACOLA (PNS) FOR GAS AND LUNCH. TOOK ON 40.2 GALLONS 100LL, TANK APPEARED TO BE FULL, WHICH SHOULD ALLOW FOR 5 HRS OF OP. FILED IFR FLT PLAN IN THE AIR WITH DERIDDER, LA, FSS AFTER GETTING UPDATED WX FOR HOUSTON. FLT PLAN ACTIVATED NEAR LAFAYETTE (LFT), RTED DIRECT SABINE VOR AND GILCO 1 ARR. WHILE BEING RADAR VECTORED TO ANDRAU AIRPARK (AAP), NOTICED FUEL PRESSURE FALLING, SWITCHED ON BOOST PUMP, THEN THE ENG QUIT. I SWITCHED TANKS, ENG RESTARTED, BUT QUIT ABOUT 10 MINS LATER AT 3000 FT MSL IN IMC. ATC VECTORED ME TOWARD AAP. I BROKE OUT AT 1700 FT MSL, BUT DIDN'T FEEL I COULD MAKE THE ARPT, SO I LANDED IN A LARGE FIELD ABOUT 1-2 MI S OF AAP RATHER THAN CHANCE GLIDING OVER THE BUILT-UP RESIDENTIAL AREA BTWN THIS FIELD AND AAP. LNDG NORMAL, NO DAMAGE TO ACFT OR PROPERTY. ON INSPECTION, TANKS WERE EMPTY. A KNOWN PROB WITH THESE TANKS IS THAT THEY SEEP FUEL ALONG THE TOP OF THE SPAR WHEN FULL, BUT THIS HAS ALWAYS BEEN VERY MINOR. GAUGES READ LOWER THAN ACTUAL, SO I WAS NOT CONCERNED WITH LOW READINGS, AND HAVE ALWAYS MEASURED FUEL BURN BY TIME. WHEN IN DOUBT, WILL REFUEL, REDUCE TRIP LEGS TO 3 HRS MAX.
