Narrative:

The following has been classified as an incident by the NTSB. In 1/89 on takeoff roll from lnd at rotation speed, approximately 95 KTS, a runway incursion and strike occurred involving 2 deer, a DOE and a fawn, in trail, crossing the runway at a run from south to north. An evasive rotation maneuver was attempted in an effort to clear the deer which was partially successful regarding the nose landing gear. Although only one moderate strike was heard on the belly of the aircraft resulting in no obvious change in engine or aircraft performance, it was determined after the fact that both deer had made contact severing the left tire, left brake and left piston from the aircraft and forcing the lower left strut assembly to be at a 45 degree angle to the rear. Minor damage was also received by the leading edge of the left horizontal stabilizer. After determining that the left tire, brake and piston were no longer attached to the aircraft, I elected to do a full gear up landing at casper and the remaining gear was retracted. After preparing the aircraft and passenger for the full gear up landing the aircraft was configured and established on a long straight in final to runway 21. The successful gear up landing was completed at casper. All persons on board the aircraft were evacuated in approximately 40 seconds west/O incident or injury. The resulting aircraft damage from the full gear up landing was limited and typical of that found in most gear up lndgs in this type of aircraft. It was learned after the fact from the airport manager that lnd has had extensive problems with game and livestock on the runway yet a fence has never been installed.

Title: ATX SMT HIT 2 DEER ON TKOF DAMAGING THE LEFT GEAR.

Narrative: THE FOLLOWING HAS BEEN CLASSIFIED AS AN INCIDENT BY THE NTSB. IN 1/89 ON TKOF ROLL FROM LND AT ROTATION SPD, APPROX 95 KTS, A RWY INCURSION AND STRIKE OCCURRED INVOLVING 2 DEER, A DOE AND A FAWN, IN TRAIL, XING THE RWY AT A RUN FROM S TO N. AN EVASIVE ROTATION MANEUVER WAS ATTEMPTED IN AN EFFORT TO CLR THE DEER WHICH WAS PARTIALLY SUCCESSFUL REGARDING THE NOSE LNDG GEAR. ALTHOUGH ONLY ONE MODERATE STRIKE WAS HEARD ON THE BELLY OF THE ACFT RESULTING IN NO OBVIOUS CHANGE IN ENG OR ACFT PERFORMANCE, IT WAS DETERMINED AFTER THE FACT THAT BOTH DEER HAD MADE CONTACT SEVERING THE LEFT TIRE, LEFT BRAKE AND LEFT PISTON FROM THE ACFT AND FORCING THE LOWER LEFT STRUT ASSEMBLY TO BE AT A 45 DEG ANGLE TO THE REAR. MINOR DAMAGE WAS ALSO RECEIVED BY THE LEADING EDGE OF THE LEFT HORIZ STABILIZER. AFTER DETERMINING THAT THE LEFT TIRE, BRAKE AND PISTON WERE NO LONGER ATTACHED TO THE ACFT, I ELECTED TO DO A FULL GEAR UP LNDG AT CASPER AND THE REMAINING GEAR WAS RETRACTED. AFTER PREPARING THE ACFT AND PAX FOR THE FULL GEAR UP LNDG THE ACFT WAS CONFIGURED AND ESTABLISHED ON A LONG STRAIGHT IN FINAL TO RWY 21. THE SUCCESSFUL GEAR UP LNDG WAS COMPLETED AT CASPER. ALL PERSONS ON BOARD THE ACFT WERE EVACUATED IN APPROX 40 SECS W/O INCIDENT OR INJURY. THE RESULTING ACFT DAMAGE FROM THE FULL GEAR UP LNDG WAS LIMITED AND TYPICAL OF THAT FOUND IN MOST GEAR UP LNDGS IN THIS TYPE OF ACFT. IT WAS LEARNED AFTER THE FACT FROM THE ARPT MGR THAT LND HAS HAD EXTENSIVE PROBS WITH GAME AND LIVESTOCK ON THE RWY YET A FENCE HAS NEVER BEEN INSTALLED.
