NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

After the airplane reached its cruising altitude of 3,000 feet, the engine lost power. The pilot cycled the magnetos and applied carburetor heat; however, engine power was not regained. The pilot then performed a forced landing to a field, during which the airplane impacted a fence. Examination of the engine revealed the magnetos did not produce spark when tested. The magnetos were disassembled and it was noted that the left magneto had a shorted condenser and the right magneto points were almost closed. The right magneto points were properly adjusted; the magneto was tested and produced spark. According to the aircraft maintenance records, the magnetos were last overhauled 40 years prior to the accident, and had accumulated 500 hours of operation since then.

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

The failure of both magnetos which resulted in a loss of engine power during cruise flight.
