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 airplane owner/pilot stated that after completion of an aerial application flight, while returning to reload, he noticed smoke in the cockpit, then the engine lost power. The pilot initiated a forced landing in a cotton field. During the landing roll, the left main landing gear wheel separated after contact with a depression. Examination of the airplane at the accident site revealed oil on the fuselage and in the engine compartment area. The oil had come from a hole in a flexible hose that was connected to the outlet of the oil cooler. The hole was adjacent to a heat shield. The owner/pilot, who was not an A & P mechanic, had performed repairs to a baffle in the engine compartment area about 2 to 3 weeks before the accident. After the repair, there was insufficient clearance between the flexible oil hose and the heat shield.

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

improper maintenance of the airplane by the unqualified pilot/owner, by providing inadequate clearance between a flexible oil hose and a heat shield, which resulted in chafing of the hose, an oil leak, and subsequent oil starvation. A factor relating to the accident was: rough terrain in the emergency landing area.
