Flight and Engine Failure
While en route from Destin, Florida, to Houston, Texas, a passenger observed the pilot periodically switching fuel tanks. The passenger also noted beeping sounds, which ceased after the autopilot was turned off and the automatic pitch trim circuit breaker was pulled. As the flight approached Anahuac, Texas, during darkness, the engine lost power. The pilot managed to restart the engine, but seconds later it lost power again and would not restart.
Emergency Landing and Wreckage
During the subsequent emergency landing, the airplane collided with trees and came to rest partially submerged in water.
Fuel Selector and Engine Tests
Examination of the wreckage revealed that the fuel tank selector was positioned between the left and right tank positions. Subsequent engine test runs were successful, indicating no mechanical failure with the engine itself.
Toxicology Results
A toxicology test of the pilot's blood showed 0.583 mcg/ml fluoxetine (Prozac) and 0.254 mcg/ml norfluoxetine (a metabolite of fluoxetine). A test of the pilot's urine showed 0.344 mcg/ml fluoxetine and 0.195 mcg/ml norfluoxetine. Prozac is a prescription antidepressant that is not approved for use while flying.
