What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The suas operator did not verify all landing legs were appropriately secured prior to flight. During flight, the left landing gear leg fell off the aircraft. The suas operator elected to have his coworker try to "catch" the UAS. Once the coworker was able to grasp the attached landing leg, the UAS attempted to correct to maintain it's last commanded position. This casued the aircraft to become unstabilized, striking the coworker multiple times and causing injury.
