Probable cause

The loss of the number five cylinder in flight, resulting in a loss of engine RPM. The pilot misjudged the landing flare height due to obscured vision from fire and smoke and the airplane stalled and impacted the ground nose first.

Analysis

The ag airplane was applying fertilizer on a field when the engine lost power. During the forced landing, the airplane stalled and nosed over after landing in a soy bean field. Post accident inspection revealed the number five cylinder was missing from the engine case. From the time the engine lost power, until the airplane touched down, there was fire and smoke coming from the engine compartment which obscurred the pilot's vision.
