What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
While overhead at the scene the aircraft was diverted to a rural fire station helipad. At the time the pilot reports it was drizzling. Nvg's were being used during the flight including the approach and landing. The pilot terminated at a hover but was having difficulty seeing his surroundings. He drifted to the rear and put the tail rotor into a fence damaging the tail rotor blades. After removing his nvg's, the pilot saw that his wind screen had fogged over. Pilot shut down the aircraft and noticed the damaged tail rotor blades during post flight.
