The airplane was north of the airport at 8,000 feet in bound for landing when she turned on the fuel boost pumps and switched from the auxiliary to the main tanks following a momentary surge. Minutes later, the left engine began to surge again. She was able to substantially restore power to the left engine. During approach to landing, the power on the left engine began to surge again, followed by a partial loss of power. As she flared for landing, the aircraft veered to the left and departed the runway into the grass. Based on the pilot's fuel calculations, the aircraft should have had 53.2 gallons of fuel remaining when she landed. The day after the accident, fuel was found in the right main fuel tank; however, the left tank was compromised and the presence of fuel could not be verified. Following the accident, the left engine was run in a test cell. The engine operated up to the maximum available power, and no discrepancies were observed. The turbocharger was also examined, and no abnormalities were found.
Probable Cause: A partial loss of power on the left engine for undetermined reasons. A factor was the pilot's failure to maintain directional control of the aircraft during landing flare/touchdown.
