Accident Description
A pilot reported that after taking off at night, he raised the landing gear, started a turn to the outbound heading, and adjusted both propeller controls. He then turned on the overhead light, adjusted the heat by moving both selector levers to the center position, and continued climbing. He had started to adjust the mixture controls when air traffic control gave him a frequency change. At that moment, both engines lost power without warning. The pilot declared an emergency and attempted to restart the engines but was unable. He then 'cut' the mixture controls and executed an emergency wheels-up landing in a field. The airplane sustained substantial damage.
Investigation Findings
An investigation revealed that there was sufficient fuel in the tanks and no contaminants were found. Fuel flow was established from the fuel tanks to the fuel control units using the electric fuel pump. The left engine was started and run through tests with no anomalies noted. The right engine could not be run due to its unsafe condition, but an examination of the engine revealed no anomalies.
The investigation did not determine a probable cause for the dual engine power loss.
