Investigator assessment
Analysis narrative
The pilot of the tailwheel equipped airplane reported that about 30 minutes from the destination airport the engine lost all power. The pilot conducted a forced landing to a rough field, during which the left main landing gear collapsed, resulting in substantial damage to the left wing and fuselage. Postaccident examination of the airplane revealed that the fuel tanks contained no usable fuel. The pilot stated that during his preflight inspection, he did not visually verify the fuel levels in the fuel tanks and relied on the fuel analyzer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
