## Probable cause

PILOT'S FAILURE TO PROPERLY CONTROL THE AIRCRAFT WHILE CONDUCTING A CROSSWIND TAKEOFF.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - compensation for wind conditions - improper, pilot in command (cause)
- On ground/water collision with object, takeoff - roll/run
  - object - fence

## Analysis

WHILE ON TAKEOFF ROLL IN GUSTY CROSS WIND CONDITIONS THE PLT FAILED TO MAINTAIN DIRECTIONAL CONTROL OF THE ACFT AND DEPARTED THE RIGHT SIDE OF THE RUNWAY. THE PLT FAILED TO REDUCE PWR AND THE ACFT PROCEEDED ACROSS A GRASS AREA BETWEEN THE RNWY AND TAXIWAY, BECOMING AIRBORNE WHEN THE LANDING GEAR STRUCK THE TAXIWAY LIP. THE ACFT STRUCK A CHAIN LINK FENCE AFTER BECOMING AIRBORNE AND FLIPPED INVERTED INTO A LAKE BORDERING THE ARPT. BOTH THE PLT AND PAX EXITED THE ACFT THROUGH WINDOWS AND SWAM TO SHORE.
