Circumstances:
The aircraft crashed into a ditch off the departure end of the runway and burst into flames during takeoff. Witnesses said the aircraft did not sound like it was developing normal rpm for takeoff. One mechanic said the engines sounded like they were still in ground idle position. The surviving passenger said they didn't get enough speed to takeoff but he did not suspect any engine problems. Another ground witness said it sounded like the propellers were in very high or cruise pitch. After the accident both propellers were at or near the feather position. Toxicology studies on the pilot showed his blood alcohol level was 2,2‰. He also had cirrhosis of the liver. A passenger was seriously injured while the pilot and a second passenger were killed.
