Primary finding
Probable cause
The pilot’s use of engine beta prior to ensuring the tailwheel was on the ground during landing roll.
Investigator assessment
Analysis narrative
The pilot stated that the approach to land was fast. During landing rollout, he used engine beta to slow the airplane while the tail of the airplane was not on the ground. Subsequently, the airplane nosed over, which resulted in substantial damage to both the top wings, empennage, and engine mounts. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
