What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
While on functional check flight after maintenance, pilot accrued 3 hours of flight when the engine stopped running due to fuel starvation. Enough fuel was found in the aircraft for at least 3 more hours of flight.
Post-incident investigation revealed that the left tank was full of fuel and right tank was empty. There is no fuel selector between tanks -both drain to " t" fitting and then to engine.
Post-incident disassembly of the aircraft revealed a "mud daubber" nest in the left fuel tank main line to the engine, thereby blocking fuel flow.
The aircraft had been disassembled for several months prior to repair and flight.
