At about 1700 eastern time, a Cirrus SR-20 was damaged on landing at Mason County Airport. The student pilot and passenger received minor injuries. The pilot said he spotted four deer on the runway while he was on final approach. He adjusted his approach to land beyond them and the airplane touched down 700 to 1,000 feet past the deer. At that point, the pilot spotted three more deer to his right front about 50 to 75 feet away, and crossing the runway. The pilot added power and pitched the nose of the airplane up but the airplane struck two deer, departed the side of the runway and went into a line of trees.
