What happened
The pilot departed with a known low battery and unequal fuel levels, consisting of 15 gallons in the left tank and 30 gallons in the right tank. While cruising at 7,500 feet, the pilot experienced a power loss on the left engine. Following emergency procedures, the pilot was unable to achieve a restart and subsequently feathered the propeller. After setting up the crossfeed, the right engine failed a few seconds later. The pilot attempted to restart the right engine but was unsuccessful, leading to the feathering of the second propeller.
At the time of the dual engine failure, both fuel selectors were set to crossfeed. The pilot reset the selectors to the tank-to-engine position and attempted another restart of the right engine, but the low battery prevented a successful restart. The pilot performed an off-airport landing on a roadway.
The investigation
A post-crash examination of the aircraft revealed that there was fuel remaining in the right tank, but no fuel was present in the left tank.
