Aircraft Accident/Incident Report
Anchorage, Alaska 99502
Tuesady, May 25, 1999 AKD
NTSB Narrative Summary Released at Completion of Accident
A twin engine turboprop airplane had been cleared for landing, and was on the downwind portion of a scheduled Title 14 CFR Part 121 flight during night visual meteorological conditions. The airplane was about 1,800 feet msl, about 2 miles southwest of the destination airport that is located in a coastal area. The flight crew briefly observed several birds, and then felt an impact. Upon landing, damage to the leading edge of the left wing was discovered. Small portions of a bird were found on the leading edge. The crew could not identify the size and type of bird. Examination of the damage to the wing revealed denting of the leading edge, and wrinkling of the upper wing surface about 4 feet inboard from the left wing tip. An internal examination of wing disclosed two broken nose ribs. Forensic examination of biological material taken from the airplane's wing was conducted by the U.S. Department of Agriculture. The material was identified as a Common Eider.
NTSB Probable Cause Narrative
