Investigator assessment
Analysis narrative
The pilot attempted to start the engine of the Cessna 172, but was unsuccessful, so he decided to "hand-prop" the engine. As he rotated the propeller from right to left, the engine started, and the airplane began to roll forward. The airplane continued across the airport ramp and impacted two other airplanes before it came to a stop. The accident airplane received substantial damage to its fuselage, and both parked airplanes were also substantially damaged.
