MIA00LA079

The pilot stated that after landing, all four fuel tanks were filled. He performed a preflight to the airplane and started both engines with no discrepancies noted. While taxiing to takeoff he performed a flight control check of the ailerons and while looking at the left aileron, he noted discoloration of the paint on the upper wing surface outboard of the engine nacelle. He requested fire rescue assistance from the ground controller and taxied to an open area of the ramp, where he secured the airplane. After exiting the airplane he noted fire at the outboard fuel tank vent that was leaking fuel. He discharged a hand held fire extinguisher he obtained from the airplane and nearly extinguished the fire. The airport fire rescue then responded and extinguished the fire using only water. According to the airport fire department incident report, vented fuel ignited by exhaust manifold was cited as the 'preliminary cause' of the fire.
