Analysis
Acft was on a medivac flt and was taking off on rwy 03 at Lander, WY. During the takeoff roll, plt saw two deer running across rwy and rotated acft abruptly to avoid collision. He felt 'moderate' impact. After determining left main landing gear had been damaged, plt diverted to casper, WY, where there was longer, wider rwys and CFR facilities. After burning off excess fuel, plt made intentional wheels-up landing. Acft was evacuated in 40 sec. Post acc investigation revealed parts of the left main lndg gear and two dead deer on the takeoff rwy at Lander.
