Accident Overview
During takeoff from Rancho California Airport, the aircraft experienced a total power loss of the right engine. The aircraft subsequently crashed approximately half a mile northwest of the airport. The pilot reported that the aircraft would not climb and could not maintain altitude at about 40 feet above ground level. When attempting a right turn to avoid a building, the pilot stated that the aircraft's speed 'probably' went below VMC.
Engine Examination
Examination of the right engine failed to reveal any failure of the rotational or mechanical systems. However, oil from an unknown origin was found on the carburetor air side. According to the source, in a pressure carburetor, any contaminants could cause an immediate power loss.
Pilot Report
The pilot provided a statement indicating the aircraft's performance issues during the attempted takeoff. The inability to climb and maintain altitude, combined with the subsequent speed reduction during the turning maneuver, were noted.
