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 aerobatic tailwheel airplane sustained substantial damage during landing on a 50 foot wide grass runway when the airplane exited runway 26, impacted high vegetation, and nosed over. The pilot stated, "Normal approach - 100 mph, 900 [feet above ground level] downwind pattern. Touched down center of runway, plane was on the ground and rolling. Everything felt right and normal. Started pulling to right added left rudder, right wing contacted wheat along edge of runway and pulled plane into [field.]" At 1854, the recorded wind was 070 degrees at 7 knots. An examination of the landing gear components disclosed that the left main landing gear fractured/separated during the accident sequence. Portions of the left main landing gear were sent to the NTSB Materials laboratory for analysis. The examination disclosed that the fractures/separations were consistent with overload, with no evidence of any pre-existing anomalies.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain directional control during the landing roll, which resulted in a loss of control, and an on-ground collision with terrain.
