Analysis

Acft lost pwr on the left eng during climb to cruise aprx 8 minutes after takeoff. Arpt mgr heard UNICOM transmission from N36CA, 'we lost an eng, we're coming back.' A warning horn (possibly gear warning or stall horn) was heard in the background of the transmission. When N36CA failed to return the arpt mgr called the sheriff & began search in his own acft. N36CA was located aprx 1 hour after it's departure. The forced landing was in a flat, wings level attitude with 22DEGS of flaps extended. Initial impact occurred in area of 8 ft high brush. Distance from initial impact to final rest was 595 ft on heading of 140 degs. Although restrained by lap belt and harness, plt hit head on co-plt's contol yoke during the accident. The left eng turbine blade had failed in fatigue. The plt's son said his father shut down the righteng in-flt and as a result the acft had no pwr on either eng.
