Probable cause

The improper level off which resulted in a hard landing. Contributing was fuel starvation resulting in partial loss of engine power.

Analysis

The pilot was en route when he radioed air traffic control he lost power in one of the engines. ATC lost radio contact with the pilot soon afterwards. Witnesses reported the airplane circled and then landed in a field. The airplane landed hard and then rolled over. Collapsing the fuselage. The examination of the airplane revealed rotational damage to the right propeller, and relatively no damage to the left propeller. An inspection of the right engine revealed fuel in the fuel pump and fuel injector unit; however, the same components of the left engine were absent of fuel. The leakage of fuel from the fuel tanks associated with the airplane damage precluded determination of the fuel aboard when the accident occurred.
