Probable cause
The pilot's failure to maintain airspeed which resulted in an inadvertent stall. A contributing factor was the loss of engine power as result of the fracture of the number two piston to crankshaft connecting rod.

Read the full NTSB narrative
On the third lap of an International Formula One Air Race the pilot aborted the race and turned south toward the center of the airport after experiencing a complete loss of engine power. The private pilot performed an emergency descent with an intended landing on runway 35R (a 3,502-foot-long and 75-foot wide asphalt/concrete runway). Near the approach end of runway 35R and approximately 50 feet above ground level (agl), the airplane stalled and started to spin to the left. Subsequently, the airplane impacted the edge of runway 35R in a near vertical nose-down attitude before coming to rest in an inverted position. An examination of the modified four-cylinder engine revealed the loss of engine power was due to a fracture of the number two piston to crankshaft connecting rod.
