N799CZ received minor damage and N84VV received substantial damage. There were no injuries to either the pilot of N799CZ, or the student pilot and flight instructor on-board N84VV. N799CZ was operated as a Title 14 Code of Federal Regulations (CFR) Part 135 cargo flight, and N84VV was operated as a Title 14 CFR Part 91 instructional flight. The pilot of N799CZ reported that after starting the airplane’s engines, he set the parking brake and then turned around to turn on the airplane’s oxygen bottle which was located behind his seat. While turned he noticed what he thought was a loose cargo strap but discovered that the strap was not loose. When he turned back around the airplane had moved and the propellers began striking the tail of the other airplane. He stopped and shut down the airplane. Both the flight instructor and student pilot of N84VV reported that they had completed their preflight inspection of N84VV and had started the airplane’s engine and were stationary. As they were preparing to taxi, they felt the airplane getting struck by N799CZ. They noted that they did not see N799CZ from the cockpit before the collision. Following the collision, they shut down the airplane and deplaned. N84VV received substantial damage to the left horizontal stabilizer, left elevator, vertical stabilizer, rudder, left wing flap and left wing aileron. ## Sequence of events The events NTSB coded, in order, by phase of flight.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
