On April 25, 2000, at 0750 eastern daylight time, a Saab SF-340B, N404XJ, operated by Mesaba Airlines as Northwest Airlink flight 3233, collided with two deer during a takeoff ground run at the Houghton Memorial Airport, Hancock, Michigan. The Captain, First Officer, Flight Attendant, and 18 passengers were not injured. The airplane received substantial damage. The 14 CFR Part 121 flight was operating in visual meteorological conditions on and IFR flight plan. The first officer (flying pilot) reported that during the takeoff run, the captain noticed a group of about seven deer approaching the runway. The first officer aborted the takeoff; however, the airplane contacted two deer which ran onto the runway. The deer contacted the left engine/propeller which automatically shut down. The airplane then taxied to the gate without further incident. The collision occurred approximately 3,000 feet down the runway which was 6,501 feet long and 150 feet wide, just prior to the airplane reaching V1. The operator reported the left engine gearbox was damaged. The engine compressor case was cracked 120 degrees around its circumference. Two propeller blades completely separated from the hub. The forward portion of the engine nacelle was twisted and the longerons which attach the nacelle to the wing were cracked.
