Birdstrike involving a Hughes Helicopters 269C, VH-ACD, 15km E Leopold Station, WA on 28 August 1993

The helicopter flew through a flock of birds. The pilot felt and saw a number of birds strike the main rotor and also saw bird remains travel rearwards after this main rotor contact. After a short time of further flight with no apparent problems, the pilot heard a "bang" from the rear of the aircraft. He saw that the rear of the aircraft was vibrating so elected to land immediately. During the landing, the tail rotor contacted the ground.
