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 reported that he did not fill the fuel tanks before departing and while en-route the left fuel tank was exhausted and he switched to the right fuel tank. Upon reaching 3,000 feet during the descent to the destination airport, the right fuel tank was exhausted and the engine lost power. The pilot reported that when the engine lost power, the "fuel totalizer showed 30 minutes of fuel remaining, but both fuel level sender units read zero". The pilot reported that he realized the airplane would not glide to the intended airport and opted to land on a driveway at a local farm. During the forced landing the airplane struck wood and metal fence posts before the right main wheel dug into the grass and spun the airplane approximately 90 degrees to the right. The airplane sustained substantial damage to the left wing spar. The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
