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 stated that, during taxi and takeoff, he set the engine fuel mixture control to the full-rich position. While in the crosswind turn, the engine lost partial power, and the pilot made a forced landing in a forested area. Examination of the engine revealed that the No. 1 cylinder’s spark plugs were completely carbon-fouled and that the Nos. 2 through 4 cylinders’ spark plugs were badly sooted. It is likely that the pilot did not properly manage the engine mixture, which led to an over-rich fuel mixture condition during the takeoff and resulted in a partial loss of engine power.

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

The pilot’s improper management of the fuel mixture, which resulted in an over-rich fuel mixture condition and a subsequent partial loss of engine power.
