## Probable cause

DEER ON THE RUNWAY. OTHER RELATED FACTOR WS A DARK NIGHT.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- On ground/water collision with object, landing - flare/touchdown
  - object - animal(s) (cause)
  - light condition - dark night (contributing factor)
- Main gear collapsed, landing - flare/touchdown

## Analysis

THE COMMERCIAL PILOT WAS LANDING ON RUNWAY 7 WHEN A DEER ENTERED THE RUNWAY. THE PILOT STATED THAT HE PULLED UP ON THE CONTROL YOKE TO AVOID HITTING THE DEER; HOWEVER, THE DEER STRUCK THE HORIZONTAL STABILIZER CAUSING HIM TO LOSE PITCH CONTROL. HE STATED THAT HE ADDED POWER TO CUSHION HIS DESCENT DURING THE SECOND TOUCHDOWN ATTEMPT, BUT THE AIRCRAFT ASCENDED INTO THE AIR. THIS ACTION CONTINUED FOR ABOUT EIGHT TIMES UNTIL THE LEFT MAIN GEAR BROKE OFF AND THE AIRCRAFT SLID TO A STOP OFF THE RIGHT SIDE OF THE RUNWAY.
