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 student and flight instructor reported that, during their preflight inspection, 4.5 quarts of oil was in the engine and the fuel tanks were full. Another quart of oil was added to the engine, and the flight departed. About 1 hour 40 minutes into the flight, the engine began to run rough. The engine subsequently stopped running and attempts to restart it were unsuccessful. The flight instructor force landed the airplane in a field, and it nosed over, resulting in substantial damage to the wings. During the recovery of the wreckage, the fuel tanks were drained, and each tank contained about 1 quart of fuel. There was no oil or fuel on the ground under the wreckage. The oil dipstick showed no oil on the stick. About 1 1/3 quarts of oil were drained from the engine. According to the engine manufacturer, the minimum safe quantity of oil in the sump is 2 quarts. Examination of the wreckage revealed no evidence of an oil leak anywhere on the engine or airframe. The engine showed evidence of seizure due to a lack of lubrication. The engine oil and filter were reportedly changed during a 100-hour inspection that occurred 3 days before the accident. Although the crewmembers reported that they departed with sufficient oil and fuel, the physical evidence does not support that assertion; the lack of lubrication led to the loss of engine power.

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

The pilots’ operation of the airplane with an insufficient supply of engine oil, resulting in engine seizure and total loss of engine power.
