The solo student pilot reported that while on a cross country flight the airplane's engine started to "sputter" and then stopped. During the off airport forced landing the airplane impacted a ravine.

According to the student pilot, prior to the loss of engine power, there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

The airplane sustained substantial damage to the engine mount.

The airplane recovery specialist reported that he drained about two gallons of fuel from the airplane's fuel tanks prior to the airplane being moved. According to the manufacturer the airplane has 3 gallons of unusable fuel.

As a safety recommendation the student pilot reported that he should have visually inspected the fuel with a fuel hawk dipstick.
