Incident Overview
On an unspecified date, a twin-engine aircraft experienced a total loss of power in its left engine during the initial climb after departing from Runway 22 at Wausau Downtown Airport in Wausau, Wisconsin.
Pilot Actions and Preflight
The pilot reported moving his flight bag from between the seats earlier. He stated that upon reaching the approach end of Runway 22, he completed an abbreviated preflight checklist, which included an engine run-up, magneto checks, propeller checks, instrument checks, and control checks. At the end of the runway, the pilot pushed his flight bag—described as a canvas attache case with outside pockets and a strap—between the front seats.
Post-Incident Findings
After the event, the throttle, propeller, and mixture controls were found in their forward positions. Engine control continuity was established. The left engine propeller was not feathered, and the landing gear was in the down position. Both fuel selectors, located between the pilot's and copilot's seats, were found in the crossfeed position.
Engine and Fuel System Examination
The left engine was removed from the aircraft and run on a test stand, where it operated normally. Examination of the fuel system revealed no obstructions in the fuel lines or fuel filter screens.
