NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that he was flying as one of a group of seven airplanes in an air race, and, during lap four, the engine lost all power. The pilot increased altitude to 2,000 feet above ground level and entered the landing pattern but had to extend his downwind to avoid traffic still on the race course. The wind took him further away from the runway than he intended so that when he turned toward the runway, he could not complete the turn to the runway heading, and intercepted the runway on a 50-degree angle at an intersection with another runway. The airplane rolled across the intersection, onto a taxiway, and continued onto a dirt ramp before cartwheeling and coming to rest in the dirt about halfway between the taxiway and the runway. Postaccident examination of the engine found that a connecting rod bearing and two connecting rods in the engine fractured and separated, which resulted in the loss of engine power.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: Failure of a connecting rod bearing and two connecting rods, which resulted in a loss of engine power while maneuvering at low altitude. Full narrative available
