## Sequence of events

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

- In flight collision with terrain/water, takeoff - initial climb
  - weather condition - unfavorable wind (contributing factor)
  - weather evaluation - inaccurate, pilot in command (cause)
  - terrain condition - rising (contributing factor)
  - proper climb rate - not attained, pilot in command (cause)
  - weather condition - downdraft (contributing factor)
  - clearance - not possible, pilot in command (cause)

## Analysis

HE DEPARTED THE LAKE TOWARDS THE EAST AND WHEN ABOUT 350 AGL ENCOUNTERED A DOWNDRAFT THE ACFT SETTLED INTO THE TREES WITH FULL POWER ON.
