On October 11, 2004, about 0919 Alaska daylight time, a wheel-equipped Cessna 207 airplane, N5277J, operated by Hageland Aviation Services under Title 14, CFR Part 135 as scheduled commuter Flight 63, sustained substantial damage when it struck a bird while on final approach to land at the Chefornak airport, Chefornak, Alaska. The commercial pilot and two passengers were not injured. The flight departed Kipnuk, Alaska, about 0900, and was en route to Chefornak. Visual meteorological conditions prevailed, and a VFR flight plan was in effect. During a telephone conversation with the operator's director of operations on October 14, he related that the accident pilot reported that a large bird, possibly a Ptarmigan, struck and penetrated the airplane's windshield. The pilot was able to continue the landing approach, and made an uneventful landing. The director of operations reported that due to the bird strike, the windshield had to be replaced.
