Pre-Start Procedures
The pilot prepared the airplane on the ramp by securing it with a rope tied to the tail, as wheel chocks were unavailable. This method was chosen to prevent movement during engine start. The engine was started by hand-turning the propeller.
Breaking of Restraint
Upon engine start, the rope that was retaining the airplane in place broke. The pilot attempted to physically hang onto the airplane in an effort to regain control and stop its movement, but this attempt was not successful.
Movement and Collisions
The airplane, now without the pilot aboard, moved across the ramp. It first struck a parked aircraft. After that impact, it hit a fence. The airplane then came to rest with its nose against the fence.
Conclusion
The pilot was not injured. The airplane sustained damage from the impacts. There were no other injuries.
