Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel equipped airplane reported that about 2 miles east of the destination airport the engine began to run rough. He elected to make a precautionary landing to an open field, while on approach to land, the engine lost all power. During the landing roll the airplane impacted a ditch, which resulted in substantial damage to the left wing. Postaccident examination of the airplane by the pilot 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.
