Analysis

This was the initial test flt after installation of rebuilt wings. On the takeoff roll, the acft began drifting to the right & the plt corrected with left aileron. He stated that the acft 'whipped violently further to right, caught a wing tip & ground looped.' An exam disclosed that the aileron bellcrank was improperly installed causing the ailerons to respond in reverse.
