## Sequence of events

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

- In flight encounter with weather, takeoff - initial climb
  - weather condition - downdraft
  - directional control - not maintained, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

AFTER THE PILOT PERFORMED A RUN UP AND ALL APPEARED NORMAL A GROUND RUN WAS COMMENCED. ABOUT 700' DOWN THE RUNWAY TRIM WAS SET TO CLIMB OUT AT ABOUT 76IAS. HOWEVER, THE PILOT STATED THAT A BAD DOWNDRAFT WAS ENCOUNTERED. A CHECK OF THE AIRSPEED WAS OK. AT 200 FT A DOWNDRAFT AND TAILWIND WERE ENCOUNTERED AND THE AIRCRAFT CONTINUED TO DESCEND AT A RATE OF 50-75' A MINUTE. THE AIRCRAFT IMPACTED THE GROUND AT THE END OF THE RUNWAY IN ABOUT 3' OF SNOW. THE PLT'S FLT TIME WAS NOT REPORTED.
