Analysis
During takeoff, there was a partial loss of engine power. The pilot jettisioned the chemical load, but was unable to clear an embankment beyond the end of the runway. After hitting the embankment, the aircraft nosed over & began burning. An investigation revealed the power loss was due to failure of a supercharger bearing.
