Investigator assessment
Analysis narrative
The flight instructor reported that while performing a touch-and-go landing at night, just prior to rotation speed, the pilot receiving instruction noticed a deer coming from the infield area. The flight instructor also saw a deer and heard a “clump” noise. The flight instructor reduced the engine power to idle and exited the runway. After taxiing to the ramp, the pilot and flight instructor noted damage to the airplane and subsequently airport operations personnel found one deceased and one injured deer near the landing runway. The deer strike resulted in substantial damage to the left horizontal stabilizer. The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
