The pilot reported that, one hour en route to the destination airport, the turbulence was getting bad, so he decided to return to the departure airport. Subsequently, the airplane ran out of fuel and he made an off-airport landing in an open field. Upon landing, the airplane bounced, the nose gear collapsed, and the airplane nosed over.

The airplane sustained substantial damage to the right wing and fuselage.

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