Primary finding
Probable cause
The total loss of engine power due to a short in the voltage regulator, and the lack of suitable terrain for the pilot to make the forced landing on.
Investigator assessment
Analysis narrative
During the takeoff climb the pilot smelled what he thought was burning electrical wires, and the cockpit filled with smoke. The engine lost all power almost immediately. The off airport forced landing on the mud flats resulted in substantial damage to the airplane when it nosed over. Examination found that the voltage regulator had shorted out. This caused a brief localized fire which burned and shorted out the magneto 'p' leads, causing the engine to stop running.
