PILOT IN COMMAND ATTEMPTED TAKEOFF WITH OVERLOADED AIRPLANE FROM ROUGH RIVERBAR STRIP AND COLLIDED WITH TERRAIN. AIRPLANE EQUIPPED WITH MANUFACTURER'S AFTER-MARKET 32 GALLON BELLY TANK WHICH ALLOWED AIRCRAFT GROSS WEIGHT TO EXCEED MAXIMUM CERTIFICATED WEIGHT ANYTIME 10 GALLONS OF FUEL AS WELL AS MINIMUM CREW WERE ABOARD. THE AIRCRAFT WOULD ALWAYS BE OVER GROSS WEIGHT WHENEVER THE REAR SEAT WAS OCCUPIED. NO CAUTION BY MANUFACTURER OR FAA REGARDING LIMITATIONS ON USE OF PASSENGER SEAT WITH BELLY FUEL.
