What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The day of the accident the wind was calm and the prevailing weather was VMC. The PIC was flying the aircraft from the front seat and performed the takeoff. After liftoff, the instructor pilot in the rear seat retarded the throttle to simulate an engine failure after takeoff. The PIC responded by lowering the pitch of the aircraft and completed a wheel landing normally. When the tailwheel contacted the runway surface it began to shimmy violently which forced the aircraft to veer to the left. The aircraft exited the east side of the runway and ground looped in a counter-clockwise turn approximately 20 feet off of the runway surface. The aircraft's right main gear broke upon completion of the ground loop turn and a small brake fire ensued. The propeller slightly impacted the turf alongside of the runway shortly after leaving the runway. The aircraft sustained substantial damage due to damage to the right hand wing.
