The pilot’s inadequate fuel planning, which resulted in a loss of engine power due to fuel starvation.

Read the full NTSB narrative
The pilot reported that, while in a climb on the left crosswind leg of the airport traffic pattern, the engine stopped producing power. He made a left turn toward the airport, activated the electric fuel pump, and changed the fuel selector valve position from the left-wing fuel tank to the right-wing fuel tank. Despite the pilot’s attempts, the engine would not restart, and the pilot made a forced landing in a vineyard. The pilot stated that he believes he unported the available fuel in the left tank while in the climbing left-hand turn. The left wing and left elevator were substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
