Probable cause

The failure of the main landing gear during the forced landing due to corrosion and fatigue. A factor was the power loss due to a fractured crankshaft.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot experienced a total power loss while en route during an aerial application flight. He subsequently landed in a wheat field. During the roll out, the airplane encountered a rise in the terrain and both main landing gear wheels separated from the struts. Examination of the engine revealed a broken crankshaft. Examination of the landing gear revealed corrosion on the inside walls of the struts and evidence of pre-existing cracks.
