## Probable cause

THAT THE FLIGHT ENCOUNTERED WINDSHEAR AND THAT AIRCRAFT CONTROL WAS NOT POSSIBLE.

## 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 - windshear (cause)
- Loss of control - in flight, takeoff - initial climb
  - aircraft control - not possible, pilot in command(cfi) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - runway

## Analysis

THE FLIGHT WAS A CFI INSTRUCTIONAL FLIGHT.  THE CFI/PIC WAS OCCUPYING THE LEFT FRONT SEAT AND THE CERTIFICATED COMMERCIAL PILOT/CFI TRAINEE OCCUPIED THE RIGHT FRONT SEAT AND WAS FLYING THE AIRPLANE.  THE CFI TRAINEE HAD PREVIOUSLY COMPLETED A TOUCH AND GO LANDING AND TAKEOFF.  ON THE SECOND LANDING THE AIRPLANE BOUNCED AND THE CFI/PIC INSTRUCTED THE TRAINEE TO GO AROUND.  THE AIRPLANE LIFTED OFF AND WAS CLIMBING AT THE BEST RATE WHEN THE AIRPLANE ENCOUNTERED A WIND SHEAR.  THE AIRPLANE YAWED VIOLENTLY TO THE RIGHT.  THE CFI/PIC IMMEDIATELY ASSUMED THE FLIGHT CONTROLS BUT ALL HE COULD DO WAS TO MAINTAIN A WINGS LEVEL ATTITUDE.  THE AIRPLANE CONTINUED TO SETTLE AND LANDED HARD AND CARTWHEELED. THE AIRPORT MANAGER CONFIRMED THAT VIRGA AND A DUST DEVIL APPEARED TO ENGULF THE AIRPORT WITHOUT ANY WARNING.
