Tuesady, May 20, 2008 17:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The commercial pilot departed on an aerial application flight after refueling and being loaded with a full load of fertilizer. Outside air temperature was 103 degrees Fahrenheit. The pilot was flying his first application pass shortly after takeoff when the engine stopped developing full power due to low compression on two cylinders from malfunctioning exhaust valves. The pilot was unable to maintain altitude and the airplane impacted the ground, bending the left wing spar down and aft.

NTSB Probable Cause Narrative

Two engine cylinder exhaust valves stuck open for an undetermined reason, resulting in a loss of engine power.
