Analysis

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 6,501 foot runway just prior to the airplane reaching V1.
