What happened
During the descent to pattern altitude, the pilot switched the fuel supply to the left tank. At 800 feet, the engine stopped functioning. The pilot attempted to switch back to the right tank in an effort to restart the engine, but was unsuccessful.
While performing the forced landing, the aircraft's landing gear struck a power line. The impact caused the airplane to land with enough force to collapse the nose gear.
The investigation
Post-accident inspection revealed that the left fuel tank was empty, while the right tank remained nearly full. Additionally, Texas Department of Public Safety personnel at the scene reported an overwhelming smell of alcohol emanating from the pilot. A portable breath tester administered on-site determined the pilot had a 0.149% blood alcohol concentration.
