18th of February 2010
A Cessna 208B Super Cargomaster aircraft was on a cargo flight from Arcata Airport (California, USA) to Sacramento International Airport on this day in 2010. After an uneventful flight, the aircraft was on approach to runway 16R in Visual Meteorological Conditions (VMC) and was following an IFR Flight Plan.

At approximately 300 feet AGL (Above Ground Level) the pilot saw a flock of 5 large birds. Before the pilot had time to initiate evasive action a felt an impact on the aircraft.
Immediately the aircraft rolled to the right which was corrected by the pilot with an opposite aileron input, correcting the yaw with rudder input. The aileron input was somewhat impaired, roll control was possible but somewhat heavier. The approach was continued and a normal landing was made on runway 16R.
After the aircraft came to a stop and was shut down a post-flight inspection revealed substantial damage to the right-hand wing in the landing taxi light area. Structural damage was incurred on the spar cap, which was twisted downward. The sheet metal mounting structure for the landing light assembly was torn loose. Damage was so extensive that the aileron control cables were being pushed backward out of position.
Some remains of the bird were recovered from the aircraft and sent to Smithsonian Institute for identification. This identified the bird as a tundra swan. Some specs of a Tundra Swan;
