Incident Overview
On the first flight of the day, the pilot initiated the engine start procedure. The pilot primed the engine using the mixture control and set the throttle to a "half" position. The pilot then placed his feet on the brakes. Upon starting, the engine rpm immediately reached 2,400 rpm, and the airplane began moving forward. Despite the pilot applying the brakes and reducing the throttle, the airplane continued to accelerate.
Collision and Damage
The airplane subsequently impacted a parked Cessna 206. The collision resulted in the partial separation of the right wing of the parked aircraft.
Post-Accident Examination
An examination of the airplane's engine, carburetor, throttle assembly, and brakes revealed no anomalies.
