Analysis

During cruise flight, the engine stopped and the pilot attempted to glide to an airport, but was forced to land in a cornfield, aprx one mile short of the airfield. A post-crash inspection revealed the flange of the left intermediate exhaust pipe (pn LW-15811) had cracked and become loose. This allowed hot gasses to melt and short out wiring to both magnetos. There was evidence that an exhaust clamp (pn LW-12093-5) was improperly installed. Subsequently, the exhaust flange failed.
