## Probable cause

AIRCRAFT'S FLIGHT ENVELOPE WAS EXCEEDED.

## Sequence of events

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

- In flight collision with object, takeoff - initial climb
  - object - tree(s)
  - aircraft weight and balance - exceeded, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground (contributing factor)

## Analysis

THE UNLICENSED PILOT AND TWO PASSENGERS WERE INJURED WHEN THEIR AIRPLANE FAILED TO CLIMB AFTER DEPARTING FROM A TURF RUNWAY. THE AIRPLANE COLLIDED WITH TREES AND IMPACTED THE TERRAIN RESULTING IN THE DESTRUCTION OF THE AIRCRAFT. THE AIRCRAFT WAS APPROXIMATELY 300 POUNDS OVER MAXIMUM GROSS WEIGHT AND THE PILOT WAS ATTEMPTING TO TAKE OFF WITH A LEFT CROSS WIND THAT WAS GUSTING UP TO 26 MPH.
