The movement of the airplane’s modified horizontal stabilizer trim system during an intentional high speed aerobatic maneuver that resulted in exceedence of the design stress limits of the airplane and an in-flight structural failure. Contrubuting to the accident was that the builder’s deviation from the airplane designer's original trim system.

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.
