Incident Overview
A pilot reported that the engine stopped, necessitating a forced landing. The landing was executed in a level gravel field. Upon touchdown, both main landing gear collapsed. The left landing gear subsequently penetrated the upper surface of the wing. The propeller remained in a horizontal position and sustained no damage.
Fuel System Examination
Post-landing inspection revealed that the left fuel tank contained 18 gallons of fuel, while the right fuel tank was empty. The fuel selector was found in the off position.
Engine Testing
A postaccident engine test run was conducted, during which the engine operated normally, indicating no preexisting mechanical issues.
