Analysis

The pilot reported that a few minutes after takeoff during an aerial application flight, while maneuvering to a field he intended to spray, the engine lost power and he attempted to land on a dirt road. He added that the airplane bounced on touchdown and "went off the road and struck a ditch." He further added that when the engine lost power, the fuel gauge indicated about half full. Postaccident, the pilot reported that the fuel gauge was "stuck in the middle", he did not visually check the fuel quantity prior to flight, and had exhausted the fuel supply.

The fuselage and both wings sustained substantial damage.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The Federal Aviation Administration Pilot's Handbook of Aeronautical Knowledge stated in part:

Fuel Gauges

The fuel quantity gauges indicate the amount of fuel measured by a sensing unit in each fuel tank and is displayed in gallons or pounds. Aircraft certification rules require accuracy in fuel gauges only when they read "empty." Any reading other than "empty" should be verified. Do not depend solely on the accuracy of the fuel quantity gauges. Always visually check the fuel level in each tank during the preflight inspection, and then compare it with the corresponding fuel quantity indication.
