## Probable cause

The separation of the tailwheel spring retaining clip for unknown reasons, which resulted in the loss of directional control during the landing roll.

## Analysis

The pilot stated that the tailwheel equipped airplane suddenly veered to the right during the landing roll. Despite his control inputs, the airplane continued to veer to the right, exited the runway, and impacted a hangar located adjacent to the runway. Examination of the airplane revealed that the fuselage and both wings were structurally damaged. The tailwheel spring retaining clip was found separated from the tailwheel assembly. No anomalies were noted with the flight control system.
