An examination of the airplane showed no anomalies which could have contributed to the incident. ## Factual narrative On November 28, 2005, approximately 1735 mountain standard time, an Embraer EMB-120ER, N299UX, operating as Great Lakes Airlines, Flight 708, sustained minor damage when it struck a taxiway light with its right propeller at the Denver International Airport (DEN), Denver, Colorado.

The scheduled, domestic passenger flight from Riverton, Wyoming, to DEN was being conducted on an instrument flight rules flight plan under the provisions of Title 14 Code of Federal Regulations Part 121. The captain, first officer and five passengers on board the airplane were not injured. Visual meteorological conditions prevailed at the time of the incident. The flight originated approximately 1630. The captain reported that after landing on runway 34R, he turned onto what he thought was a 90-degree taxiway. He said he "cut the corner too tight resulting in the right propeller striking a taxiway light." The first officer stated that she was switching radio frequencies and when she looked up, realized that they were too close. She said it was too late. An examination of the airplane showed leading edge damage to one blade on the right propeller. The top of the taxi light at Taxiway F-4 was sheared off. No other damage was found.
