What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot privacy data omitted stated while he was idling in his tiedown spot he reached behind him to retrieve something and inadvertently bumped the throttle of the aircraft. This bumping resulted in the aircraft lurching forward and striking another aircraft's wing (Cessna 172 N8683U) with the propeller. Minor damage was done to the bonanza's propeller and extensive damage was done to the Cessna's wing and vertical tail. The pilot privacy data omitted concluded that in future operations he would shut down his engine if he realized his cockpit was not sufficiently organized for flight.
