What happened
Shortly after departing, the left engine of the aircraft experienced a sudden loss of power. The pilot did not feather the propeller on that side. Instead, a traffic pattern was initiated while the aircraft remained in a continuous descent. As altitude decreased rapidly, it became apparent there was insufficient height to maneuver back to the runway. Consequently, the pilot chose to land on level ground near the approach end of the runway rather than attempt to reach the paved surface.
Just prior to touchdown, the landing gear was extended. The aircraft then impacted the ground with significant force. This hard landing caused the landing gear to shear off upon impact.
The investigation
Examination of the aircraft revealed that no fuel was present forward of the firewall in the fuel line supplying the left engine. Investigators found no mechanical defects or issues that would have caused a starvation of fuel to the affected engine.
