What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
After landing at field site drill pad, pilot offloaded passengers to refuel. While performing cool down prior to engine shutdown and subsequent fueling, gusty winds blew a loose super sack onto the pad and into the main rotor system. Sack entangled itself on one blade and caused sufficient damage to render blade unairworthy. Due to required sudden stoppage inspection, aircraft loaded out to deadhorse and returned to home station for teardown. Bnh
