What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot refueled the airplane at the self-service fuel pump located at Rifle Garfield County Airport (kril). After refueling the aircraft, the pilot repositioned the airplane to the ramp for startup. The pilot stated that he attempted to start the aircraft but the aircraft would not start. The pilot called a mechanic to discuss options on how to get the aircraft started. The pilot decided to start the aircraft manually by turning the propeller by hand. The pilot stated he chocked the wheels of the aircraft and set the parking brake prior to hand starting the aircraft. He then began to turn the propeller to start the aircraft. The aircraft started and the pilot stated that the propeller immediately went to high RPM. Immediately after starting the aircraft, the pilot reported that the aircraft jumped the wheel chocks and began rolling forward. The aircraft rolled into a parked Cessna 171 airplane and then hit a hangar damaging a Piper malibu airplane parked in the hangar.
