Event Sequence
While en route, the left engine suddenly lost power and could not be restarted. The pilot feathered the left propeller and allowed it to cool for approximately five minutes before attempting another restart, which was unsuccessful. Believing the engine was secured, the pilot diverted toward Indianapolis. During the diversion, the right engine began to overheat and lose power. The aircraft subsequently crash-landed in a cornfield at night with the landing gear retracted; the landing lights could not be extended.
Post-Accident Examination
Examination of the aircraft revealed that fuel remained in all tanks. However, sheriff personnel had moved the fuel selectors upon arrival, so the selector positions could not be verified. The left throttle was found full forward, the left mixture control in mid-range, and the left propeller control at full low RPM (not feathered). The left propeller was not feathered, but the right propeller was feathered; the pilot stated he feathered the right propeller just before impact.
Engine Teardown
A teardown of the left engine disclosed that the number 4 main bearing had failed. The bottom half of the oil cooler was 95% blocked by soft metal contamination, and the propeller governor mounting gasket was 75% blocked by metal contamination. Despite these failures, the left engine crankshaft would still turn.
