Preflight and Takeoff
During the preflight inspection, the pilot found water in a fuel sample. The water was drained until a clear sample was obtained. The fuel tanks were then topped off, and the remainder of the preflight inspection revealed no other anomalies.
The pilot initiated a takeoff. Upon reaching rotation speed, the airplane became airborne and the landing gear was retracted.
Loss of Power
Immediately after gear retraction, the right engine lost power. The pilot feathered the right engine and attempted to return to the airport. Shortly thereafter, the left engine also lost power. The pilot informed the air traffic controller that the airplane had lost all power.
Accident Sequence
The airplane subsequently collided with trees and terrain. A post-crash fire ensued.
Postaccident Examination
A postaccident examination of the airframe and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. Examination of fuel retrieved from the right main fuel tank, as well as fuel from the fixed base operator, revealed no anomalies.
The left fuel selector valve was observed in the plugged port (no fluid flow) position, but it was most likely moved to that position during the accident sequence. The right fuel selector valve was partially aligned with the main fuel passageway and was unobstructed.
The reason for the loss of engine power to both engines was not determined.
