Killeen Skylark Field Airport
Aircraft Accident/Incident Report

Killeen, Texas 76543
Saturday, August 10, 2013 9:27 CDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
