The Viscount was flying at 6000 feet, en route from Newark to Washington when it penetrated a flock of whistling swans. At least two of which were struck by the aircraft. One swan, which was struck penetrated the leading edge of the left horizontal stabilizer and egressed from the rear surface causing damage to the elevator as it did so.
This so weakened the structure that failure occurred which rendered the plane uncontrollable. The Viscount eventually struck the ground in a nose-low inverted attitude.
Probable Cause:
PROBABLE CAUSE: "A loss of control following separation of the left horizontal stabilizer which had been weakened by a collision with a whistling swan."
Classification:
Bird strike Wing failure
Loss of control
