Probable cause
A total loss of engine power due to the failure of the outer crankshaft seal.
NTSB analysis
While flying at an altitude of 400 to 500 feet above the ground the engine lost power. The pilot attempted to restart the engine, but was unsuccessful. The airplane contacted an embankment during an off-airport emergency landing in a corn field, resulting in substantial damage to the airplane. The pilot reported that the outer crankshaft seal on the ignition side of the engine was not fully functional, resulting in a drop in vacuum pressure and a subsequent loss of fuel pressure. The pilot did not hold a pilot certificate.
