NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot was conducting a local "shakeout" flight, as the airplane had not flown since its last inspection 9 months prior. The pilot performed a preflight inspection and observed that the fuel was "almost full" in the main tanks and "almost halfway full" in the auxiliary tanks. The pilot "sumped" the fuel tanks, and observed some water in the fuel. After departure, the airplane seemed to be operating "normally," but at a slower indicated airspeed than normal for the power setting. The pilot flew toward the nearest airport, where he also intended to purchase fuel. As the pilot lowered the landing gear on the downwind leg of the traffic pattern, he did not observe the "gear down" lights illuminate in the cockpit. Shortly after, the pilot noticed that the left engine rpm and manifold pressure were "up" but the engine "wasn't producing much thrust." The pilot cycled the landing gear and continued troubleshooting the left engine; however, the gear did not extend, and he decided to perform a single-engine go-around. During the go-around the airplane rolled to the left "near Vmc," impacted trees, and came to rest inverted in a swamp. Examination of the magnetos revealed they would not produce spark when functionally tested on a test bench. Disassembly of the magnetos revealed rust and corrosion, and that the points were insulated. It could not be deduced whether these conditions were present at the time of the accident.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain aircraft control during a single-engine go-around. A factor was the partial loss of engine power.
