Incident Description
The pilot of a Cessna T210M arrived overhead a turf USFS mountain airstrip, which has a length of 3,200 feet. An overflight was conducted to ensure the runway environment was free of objects and wildlife. After this verification, the pilot commenced an approach. The pilot later reported that the approach was "a little long but manageable." Following the touchdown, while the aircraft was still rolling at a speed of 45 knots, the pilot observed a deer entering the runway area from the right.
Given the concern that the deer would cross in front of the aircraft before the aircraft's speed could be adequately reduced, the pilot elected to abort the landing by applying full power. During this procedure, the pilot and three passengers perceived a thump. The pilot then continued the climb with the landing gear extended and diverted to Missoula, Montana.
Runway Remarks
The most recent Airport Master Record (FAA Form 5010-1) for the airstrip included an advisory in the remarks section regarding the presence of wildlife on the runway.
