The pilot said that the airplane was in cruise flight at 5,500 feet mean sea level (MSL), and three hours into the flight, when he noticed that the oil pressure indicator read zero. The pilot performed a precautionary landing in a circular hay field which contained numerous rolled bales of hay. 'I planned to land on an upgrade, which I did, halfway up. As I topped the grade, two hay bales appeared. I opened the throttle, with no response, hoping to clear the bales of hay.' The airplane's right wing struck one of the hay bales and nosed over. Examination of the wreckage showed no anomalies. There was no evidence of in-flight oil loss. In a later statement, the pilot said that the airplane's engine was consuming 1.5 to 2 quarts of oil an hour. The engine operator's manual states that the maximum oil consumption for the engine in a one hour time period at normal power (2,700 RPM) is .80 quarts.
Probable Cause: low oil level which resulted in the partial loss of engine power, the pilot's intentional operation of the airplane with a known mechanical deficiency, and the hay bale. Factors relating to this accident were the owner/pilot mechanic's failure to comply with engine operating parameters pertaining to oil consumption and the pilot's decision to perform a precautionary landing in a hay field.
