Flight Timeline
About 30 minutes after departure, the right engine lost power. The pilot attempted to restart the engine without success and subsequently secured the right engine, feathering the propeller. Shortly after the restart attempt, the pilot reported a complete loss of electrical power, rendering the radios inoperable. The pilot placed the landing gear lever in the down position and established an approach to runway 5R for an emergency landing. After touchdown, the airplane skidded off the left side of the runway.
Examination Findings
Post-accident examination of the airframe and engine assemblies did not reveal any mechanical malfunctions or component failures. A functional check of the electrical system also found no mechanical problems. When the master switch was turned on, 75% of the battery power was restored to the airplane, and the electrical power was sufficient to activate the landing gear doors. Examination of the fuel system traced fuel from the tank to the fuel control unit. The right fuel shut-off valve was found to function normally, with no mechanical issues discovered.
