Bell 47G crash near Bakersfield, CA, United States

The pilot reported that the purpose of the flight was to move the helicopter off of a trailer onto the ground. As the helicopter began to lift off from the trailer platform, a steel bolt on the landing gear skid caught on the aluminum trailer skirting. The helicopter experienced a dynamic rollover and came to rest on its right side. Shortly thereafter, a fire erupted and the cabin area was consumed. The pilot stated that there were no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
