What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft was dispatched on a hospital mission. Aircraft was at the airport, kssf, at the time. Start was normal, runup was normal, and t/o to a hover was normal. Aircraft systems checked normal, as did flight control response check and c.g. check. Aircraft received t/o clearance and right turn out on course. As the aircraft started in forward flight, pilot felt a slight vibration in the pedals as the aircraft went through etl. As the airspeed increased to approximately 65 KIAS, the pilot felt a significant vibration in the pedals and the airframe, the crew in the rear of the aircraft stated that they heard a loud rumbling sound and the vibration caused medical gear to fall out of place. Mission was aborted, aircraft returned to land at the airport and maintenance was notified. Inspection revealed a 1 inch gash on one blade of the tailrotor assembly.
