The NTSB's narrative final · quoted from the NTSB record
While en route the pilot first heard engine roughness, then observed high oil temperature indication and experienced momentary binding of the aileron flight controls. The engine oil temperature reached the maximum red line and also the engine began to run rough. He performed a forced landing in a field and during the landing roll, the nose landing gear separated and the airplane nosed over. Examination of the engine by the FAA airworthiness inspector revealed that the exhaust for the Nos. 2 and 4 cylinders were separated at the flange at the cylinder. The exhaust was manufactured by Velocity using owner/pilot purchased 16 gauge 304 stainless steel and was installed about 96 hours earlier. No determination could be made as to the reason for the failure of the exhaust.
