Analysis

The aircraft engine began to vibrate excessively and lost power. The pilot landed the aircraft in a field. The aircraft nosed over in the soft ground. Examination of the engine revealed that the number one cylinder valve spring seat lock had failed allowing the intake valve to drop into the cylinder where it was struck by the number one piston, bending the valve stem and head.
